Evaluating the ADP8861 Charge Pump, 7-Channel Smart LED Driver with I2C Interface

Analog Devices Inc.
The ADP8860SHIELD-EVALZ and the ADP8861SHIELD-EVALZ incorporate light emitting diodes (LEDs) for quick and easy evaluation of the ADP8860 and the ADP8861. Note that only the ADP8860SHIELD-EVALZ has dual light intensity sensors. The ADP8860SHIELD-EVALZ and the ADP8861SHIELD-EVALZ follow the form factor of a regular Arduino® shield to allow compatibility with microcontroller boards that use the same interface. These evaluation boards also incorporate a separate header dedicated to I2C communications. The ADP8860 and the ADP8861 are 7-channel LED drivers that utilizes a charge pump with selective gain for maximum efficiency. The LEDs driven by either device are programmable for maximum current and fade in and out times via the I2C interface. Only the ADP8860 has a programable light intensity threshold that can be set via the I2C interface of the device. Each channel can handle up to 30 mA (typical), except for the seventh channel, which can handle 60 mA (typical). Each channel can be unified to have the same fade in time and fade out time, or each channel can have an individual fade in time and fade out time for greater flexibility. For full details on the ADP8860 and the ADP8861, see the ADP8860 and the ADP8861 data sheets, which should be consulted in conjunction with the user guide when using these evaluation boards.

LTC4088 Demo Board

Analog Devices Inc.
Demonstration Circuit 1007 is a high efficiency USB power manager with PowerPath™ control and Li-Ion/Polymer battery charger featuring the LTC4088. It includes a synchronous switching input regulator, a full featured battery charger and an ideal diode. Designed specifically for USB applications, the LTC4088’s switching regulator automatically limits its input current to either 100mA, 500mA or 1A for wall-powered applications via logic control. There are also 2.5mA and 500μA suspend modes to prevent the battery from running down when the product is connected to a suspended USB bus. The switching input stage provides power to VOUT where power sharing between the application circuit and the battery charger is managed. Unlike linear PowerPath controllers, the LTC4088’s switching input stage can use nearly all of the 0.5W or 2.5W available from the USB port with minimal power dissipation. This feature allows the LTC4088 to provide more power to the application and battery and eases thermal issues in space constrained applications. An ideal diode ensures that the system power is available from the battery when the input current limit is reached or if the USB or wall supply is removed. The optional external P-channel MOSFET supplements the internal ideal diode by reducing RON and increasing efficiency. A CHRG LED indicates four possible states of the battery charger. Charging is indicated when the LED is steady-ON. Not charging is indicated by a steady-OFF. A NTC fault is indicated by a slow blinking rate (1.5Hz) and a bad battery is indicated by a fast blinking rate (6.1Hz). The LTC4088 is available in the low profile 14-Lead 4mm × 3mm × 0.75mm DFN surface mount package.

The LTC7812 is a high performance synchronous Boost+Buck DC/DC switching regulator controller that drives all N-channel power MOSFET stages. It contains independent step-up (boost) and step-down (buck) controllers that can regulate two separate outputs or be cascaded to regulate an output voltage from an input voltage that can be above, below or equal to the output voltage.

The 33?A no-load quiescent current extends operating run time in battery-powered systems.Unlike conventional buck-boost regulators, the LTC7812?s cascaded Boost+Buck solution has continuous, nonpulsating, input and output currents, substantially reducing voltage ripple and EMI. The LTC7812 has independent feedback and compensation points for the boost and buck regulation loops, enabling a fast output transient response that can be easily optimized externally.Applications Automotive and Industrial Power Systems High Power Battery Operated Systems

LT8708 80V VIN and VOUT Synchronous 4-Switch Buck-Boost DC/DC Controller with Flexible Bidirectional Capability

Analog Devices Inc.
Demonstration circuit 2596A is a high performance bidirectional buck-boost converter featuring the LT®8708 that can operate from input voltages above, below or equal to the output voltage. The demo board input range is 36V to 75V. The output voltage is set at 48V and the output current limit at 6A. The controller has integrated input voltage and output voltage regulators and two sets of input and output current regulators that control current flow in forward or reverse direction. Features are included that simplify bidirectional power conversion in battery/capacitor backup systems and other applications that may need regulation of VIN, VOUT, IIN and/or IOUT. While the current mode control limits the inductor current both in normal and in reverse direction these current limits have some variation as input/output voltage changes. The forward and reverse input and output current regulators offer four accurate current limits that can be set individually. The input voltage regulator is often used in applications with high impedance power sources and will reduce the forward current if the input voltage drops below the set point. When operating with reverse current flow the input voltage regulator regulates the voltage at the input side. The operating mode of the controller is determined through the MODE pin (jumper JP7 Pins 5 to 12) and can be set to discontinuous mode, hybrid discontinuous mode, forced continuous mode and Burst Mode® Operation. The LT8708 is capable of bidirectional operation when operating in the continuous conduction mode (CCM). DCM, HCM and Burst Mode operation only allow power to flow in one direction. Additional circuitry may be needed depending on the application. By feeding the LT8708 from a separate low voltage supply the power dissipation can be reduced. The LT8708 will start when >5.5V voltage is applied at the input (VIN pin), and when it is running it will draw current from the EXTVCC pin if the voltage at the pin is > 6.4V. Typical efficiency with 5A load is above 96.3% across a 36V to 75V input range. The LT8708 data sheet gives a complete description of the part, operation and application information. The data sheet should be read in conjunction with this quick start guide for DC2596A. The input voltage range of the LT8708 itself is 2.8V (need EXTVCC > 6.4V) to 80V and the output range is 1.3V to 80V. The LT8708EUHG is assembled in a 40-Lead (5mm × 7mm) plastic QFN package with a thermal pad underneath the chip. Proper board layout is essential for maximum thermal and electrical performance. See the data sheet Circuit Board Layout Checklist section.

Analog Devices Inc.
The LTC4041 is a complete supercapacitor backup system for 2.9V to 5.5V supply rails. It contains a high current step-down DC/DC converter to charge a single supercapacitor or two supercapacitors in series. When input power is unavailable, the step-down regulator operates in reverse as a step-up regulator to backup the systemoutput from the supercapacitor(s).The LTC4041?s adjustable input current limit function reduces charge current to protect the input supply from overload while an external disconnect switch isolates theinput supply during backup. When the input supply drops below the adjustable PFI threshold, the 2.5A boost regulator delivers power from the supercapacitor to the systemoutput.An optional input overvoltage protection (OVP) circuit protects the LTC4041 from high voltage damage at the VIN pin. An internal supercapacitor balancing circuit maintainsequal voltages across each supercapacitor and limits the maximum voltage of each supercapacitor to a pre-determined value.
