Description
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.
Features
- 3.3V and 5V dual synchronous outputs, resistor
programmable to 2.5V Fixed frequency or PSAVE for maximum efficiency over wide load current range 5V / 50mA linear regulator TM Virtual Current Sense for enhanced stability Accurate low loss current limiting Out of phase switching reduces input capacitance requirements External compensation supports wide range of output filter components Programmable power-up sequence Power good output Output overvoltage & overcurrent protect.
