The CXLB7386 is an integrated USB power switch with boost converter to meet USB 5V
power requirements from a 2V to 5V input supply. The features include a USB compliant
power output, output switch enable, thermal shutdown and current limit.The USB power
switch is an integrated 200mΩ power switch with current limiting protection at 1.4A.
The boost converter output is an auxiliary 3V to 5.5V output to power additional loads.
Its Load current can program by an external resistor from as low as 130mA to as high as
2000mA. It can operate in stable waveforms without external compensation.
