The SC1402 is a multiple-output power supply controller designed to power logic supply components in battery operated systems. The SC1402 utilizes synchronous rectified buck topologies to generate two voltages, (3.3V and 5V) with up to 95% efficiency. It also provides two linear regulators for system housekeeping functions. The 12V linear regulator output is generated from a coupled inductor of the 5V switching regulator.
