From a Li-Ion battery the PMP2631 supplies 5V @ 3A with the best possible efficiency due to the sync-boost topology.

The TPS40170 controller with a pair 60V FETs from our CSD1835x offerings provide a complete high efficiency solution for non-isolated DC/DC needs off a regulated 48V input voltage. The attached design targeted 30V output at 12A and achieved 98% conversion efficiency. The same design was then adjusted to 8V output at same current and test results for this are also attached. The attached Test Reports include thermal images both with and without forced airflow. For lower current applications or applications with significant airflow; lower cost FETs from the CSD1835x series can be used. For outputs at 12Vouts or less: even at same 12A current; a smaller output choke can be used.

The PMP4992 reference design provides an isolated 32V at 96W (3A) from a standard 48V telecom bus with 91% efficiency. This design uses the TPS40210 to control a diode rectified flyback converter for a low cost and efficient design.

PMP6584 is a high power (non-standard) Power Over Ethernet (POE) active clamp forward converter. It features the TPS23756: which is a combination of a POE Powered Device (PD) controller and PWM controller. It also utilizes an ISO721 digital isolator and TPS28225 synchronous MOSFET driver. The input accepts standard POE voltage or a 24VDC-48VDC auxiliary voltage. The output power is an isolated 8VDC at 3A.

Demonstration Circuit DC2100B-D is a stackable, bidirectional cell balancer slave board using the LTC6804-2 and the LTC3300-1 ICs to achieve active balancing of up to 12 Li-Ion cells. It requires the DC2100B-C for proper operation. The DC2100B-D uses a single LTC6804-2 Multi-Cell Addressable Battery Stack Monitor IC to measure cell voltages and two LTC3300-1 Synchronous Flyback ICs to provide active cell balancing. The DC2100B-C controller board contains a PIC18F47J53 microcontroller, the LTM2884 isolated USB transceiver, the LTC6804-2, two LTC3300-1 ICs, and the LTC6820 isoSPI Interface IC to facilitate isolated communication. Up to seven DC2100B-D boards can be connected to a DC2100B-C to build a stacked system of eight total boards.

The Texas Instruments bq27411-G1 reference design is an easy to configure fuel gauging solution for single series cell Li-Ion battery packs. The device requires minimal configuration and uses One Time Programmable (OTP) Non-Volatile Memory (NVM) to avoid an initialization download by the system processor.The bq27411-G1 uses the patented Impedance Track™ algorithm for fuel gauging: and provides information such as remaining battery capacity (mAh): state-of-charge (%): and battery voltage (mV).

A ready to use design that efficiently solves the problem of improper installation by adding antiparallel communication channels and appropriate control signal to enable polarity correction for the Controller Area Network (CAN) bus.
