Description
The SC1403ITS.TR is a multiple-output power supply controller designed specifically for battery operated systems. It provides synchronous rectified buck converter control for two power supplies, namely 3.3V and 5V. With Semtech's proprietary Virtual Current SenseTM technology and external error amplifier compensation, the SC1403ITS.TR achieves enhanced stability and DC accuracy over a wide range of output filter components while maintaining a fixed frequency operation. Additionally, it includes a linear regulator for system housekeeping, which switches to the 5V output for increased efficiency when available.
