Description

The TPS61381QEVM-126 operates over a wide back up battery voltage range of 0V to 12V and main battery (VBAT port) voltage range of 0V-40V to achieve a bi-directional operation. The EVM supports an output up to 7.5A load at 3.6V BUB and 6.2V output in boost mode, and supports 50-100mA charging current in charger mode. The TPS61381QEVM-126 can support output voltage regulation accuracy better than 2.5% in boost mode and support better than 1% voltage accuracy in charger mode. The device functions are adjustable using I2C interface.
