Texas Instruments TPS61381QEVM-126 Evaluation Module
Texas Instruments TPS61381QEVM-126 Evaluation Module is configured to evaluate the operation of the TPS61381-Q1 converter. The TPS61381-Q1 is a 40V, 15A, bidirectional boost converter and LDO charger that integrates battery state-of-health detection function.
The TI TPS61381QEVM-126 performs over a broad backup battery voltage range of 0V to 12V and a primary battery (VBAT port) voltage range of 0V to 40V to execute a bidirectional operation. The evaluation module supports output up to 7.5A load at 3.6V BUB and 6.2V output in boost mode and supplies a 50mA to 100mA charging current in charger mode. The TPS61381QEVM-126 delivers output voltage regulation accuracy of better than 2.5% in boost mode and enables better than 1% voltage accuracy in charger mode. The device operations are adjustable using the I2C interface.
