IT7831 - 5V/1A High Efficiency Synchronous Step-Down DC/DC Converter
The IT7831 is a high efficiency step-down DC/DC converter using a constant frequency, current mode architecture.
The device integrates a main switch and a synchronous rectifier for high efficiency without an external schottky diode.
The supply current during operation is only 190µA and drops to < 1µ
