Demonstration circuit DC2343A is a complete system level solution for a nanopower buck-boost DC/DC with integrated coulomb counter. The DC2343A contains a PIC16F1459 embedded processor for communication to the PC over USB and the LTC3335 via its I2C port. The GUI is capable of reading and writing all the control registers on the LTC3335 as well as displaying and resetting all its alarm registers. The firmware and software for the embedded system and the GUI are available at the LTC3335 solutions page. The DC2343A uses two analog-to-digital converter channels to sample the battery and output voltages. The voltage samples improve the functionality of the GUI, and allow optimal software correction to the measured coulombs. By adding the software correction the first order known errors are compensated for over the operating range and the resultant coulomb count is accurate to within 3%.

Demonstration circuit 2419A features the LTC3372 in a multi-output step-down converter. The controller portion of the LTC3372 drives a high output voltage (HV) buck converter which has an input voltage range of 6V to 60V. Its output voltage (VOUT_HV) is nominally 5V but can be configured for either 5V or 3.3V with the VOUTPRG pin. VOUT_HV supplies power to the configurable buck regulator. This regulator provides four low voltage (LV) outputs labelled VOUT1-4. These outputs are 1.2V/2A, 1.8V/2A, 2.5V/2A and 3.3V/2A respectively. When VOUT_HV is configured for 5V, it can supply 6A to the external loads with full load on VOUT1-4. With no load on VOUT1-4, VOUT_HV can supply 10A to the external loads. The LV buck regulator consists of eight power stages that can be arranged in up to four channels. The LV regulator on the DC2419A is setup for four channels of two power stages each. With modifications, the LV buck regulator can be setup for eight different configurations. If VOUT_HV is programmed for 3.3V, then VOUT4 which provides 3.3V/2A will be in dropout. This rail will require an external input voltage to stay in regulation. The LV rails operate at 2MHz and the HV converter operates at one-sixth this frequency or 333kHz. The high frequency of the LV rails allows the use of 4mm × 4mm inductors. The power stage for the HV converter consists of 60V avalanche rated MOSFETs and a 2.2μH 10mm × 10mm inductor. A 4mΩ discrete sense resistor is used to sense current. The low IQ current of the LTC3372 provides high efficiency at light loads. When the VOUT_HV is supplying the nominal 5V, its Burst Mode® efficiency with 1mA load is 90.3% for a 12V input. When the HV converter is off, it only draws 27μA from a 12V input. The LTC3372 data sheet provides a complete description of the IC operation and application information. The data sheet must be read in conjunction with the quick start guide.

The LTC6820 provides bidirectional SPI communications between two isolated devices through a single twisted-pair connection. Each LTC6820 encodes logic states into signals that are transmitted across an isolation barrier to another LTC6820. The receiving LTC6820 decodes the transmission and drives the slave bus to the appropriate logic states. The isolation barrier can be bridged by a simple pulse transformer to achieve hundreds of volts of isolation.The LTC6820 drives differential signals using matched source and sink currents, eliminating the requirement for a transformer center tap and reducing EMI. Precision window comparators in the receiver detect the differential signals. The drive currents and the comparator thresholds are set by a simple external resistor divider, allowing the system to be optimized for required cable lengths and desired signal-to-noise performance.Applications Industrial Networking Battery Monitoring Systems Remote Sensors

DC442A: Demo Board for the LT1950 Single Switch PWM Controller with Auxiliary Boost Converter.

The ADL5920 is an ultrawideband, bidirectional detector that simultaneously measures forward and reverse rms power levels in a signal path, along with the return loss.The forward and reverse power traveling through the integrated bidirectional bridge is measured using two 50 dB linear in dB rms detectors. The detector output voltages, available at the VRMSF and VRMSR pins, are proportional to the forward and reflected power in dBm. A third, differential, output produces a voltage proportional to the return loss (reflection coefficient) in dB, closely related to the voltage standing wave ratio (VSWR). The common-mode level of this output is externally adjustable through the VOCM pin.The primary transmission line of the bidirectional bridge, from RFIN to RFOUT (or vice versa) is dc-coupled and allows small amounts of dc bias current through the bridge. When dc-coupled to source and load, the positive and negative supply pins of the ADL5920 must be connected to +5 V and ?2.5 V, respectively (relative to the dc voltage at RFIN and RFOUT). The internal detector circuitry is also dc-coupled to the directional bridge to support measurements down to 9 kHz.The maximum input signal on each of the RF ports (RFIN and RFOOUT) is 30 dBm for open and shorted terminations and 33 dBm for a matched termination.The ADL5920 draws 160 mA from a 5 V supply and has a low power, power-down mode controlled through the PWDN/TADJS pin.The device is supplied in a 32-lead, 5 mm ? 5 mm LFCSP and is specified for ambient operating temperatures in the ?40?C to +85?C range.Multifunction pin names may be referenced by their relevant function only.Applications Industrial metering Broadband inline power and return loss measurement Transmit power control and automatic level control in wireless transmitters, signal generators, network analyzers, and wireless communications testers Condition based monitoring of system modules, cables, and connectors
