The LT3595 is a high performance LED Driver designed to drive sixteen independent channels of up to 10 LEDs at currents up to 50mA. Series connection of the LEDs provides identical LED currents resulting in uniform brightness. Power switches, Schottky diodes, and compensation components are all internal, providing a small converter footprint and lower component cost. The high 2MHz switching frequency permits the use of tiny, low pro? le inductors and capacitors. A fixed frequency, current mode architecture results in stable operation over a wide range of supply and output voltage. A single external resistor sets the LED current for all sixteen channels, and dimming is then controlled for each channel by pulse width modulating the individual PWM pins. Relative current matching among the sixteen drivers is 8% and the PWM dimming range is 5000:1. The part is available in a 5mm x 9mm x 0.75mm 56-pin QFN package.

DC1203A: Demo Board for LTC4357 Positive High Voltage Ideal Diode Controller.

Demonstration circuit 1206 is a step-down converter, using the LTC3568 monolithic synchronous buck regulator. The DC1206 has an input voltage range of 2.25V to 5.5V, and is capable of delivering up to 1.8A of output current at a minimum input voltage of 2.25V. The output voltage of the DC1206 can be set as low as 0.8V, the reference voltage of the LTC3568. At low load currents, the DC1206 can operate in either noise sensitive applications, due to the capability of the LTC3568 to operate in pulse-skipping mode, or in high efficiency applications, because the LTC3568 can also operate in Burst-Mode®. During Burst-Mode® operation, the output ripple voltage is still low – less than 30 mV – due to the improvements made in the design of the LTC3568.

The iMEMS® ADXL372 inertial sensor evaluation system is an easy-to-use evaluation tool targeting bench or desktop characterization of Analog Devices, Inc., inertial sensor products. The system consists of the inertial sensor evaluation board (ISEB), or main board, and a satellite board for any Analog Devices inertial sensor product. The ISEB connects directly to a PC via an USB cable, with the USB connection providing both communications and power to the board. The ISEB is connected to the satellite board through a ribbon cable. This cable allows the satellite to be easily manipulated for testing or separately placed into an environmental chamber for temperature or humidity testing. Separating the boards mitigates corruption of data due to the temperature and humidity effects of other components. The ISEB is an universal main board and is intended to be used with various satellites of Analog Devices inertial sensors, including analog and digital accelerometers, as well as gyroscopes. The different products are evaluated by means of separate GUIs that are customized for performance and characterization measurements relevant to the inertial sensor being evaluated. There are two kinds of mother board, one named –M and the other named –MLP. The difference between –M and –MLP is just the shunt resistor R13 and the gain resistor R17 which are used to detect the power consumption of the DUT (Device Under Test). EVAL-ADXL372-M used the –M mother board. As ADXL372 is pin-to-pin compatible with ADXL362, the ADXL362 satellite board can be reused for ADXL372. The EVAL-ADXL372Z-M system contains the ISEB and the EVAL-ADXL372Z-S satellite. Also included is an USB A to Mini-B cable to connect the ISEB to a PC and an 18-inch, 20-pin ribbon cable to connect the ISEB to the satellite.
