The ACT510x is a buck-boost converter with 4 integrated MOSFETs. It offers a high efficiency, low component count, compact solution for a wide input voltage range from 4V to 23V applications. An advanced switch control algorithm allows the buck-boost converter to maintain output voltage regulation with input voltages that are above, below or equal to the output voltage. The system can be monitored and configured by I²C as well. The build in ADC (ACT5101) can be read for the information of input/output voltages and currents, die temperature, and generic input signals.
