SC1403 - Mobile Multi-Output PWM Controller with Virtual Current SenseTM
The SC1403 is a multiple-output power supply controller designed to power battery operated systems.
The SC1403 provides synchronous rectified buck converter control for two (3.3 V and 5 V) power supplies.
An efficiency of 95% can be achieved for the two supplies.
The SC1403 uses Semtech’s proprietar
SC1403 Features
