The LTC3756 is a 3V/3.3V low voltage multi-output switching regulator that supports two input power sources and can single-stage convert from either input power source. It supports up to 800mA of output current, features high efficiency, and low power consumption.
The LTC3101 is a single-IC power management solution designed to maximize efficiency while minimizing space requirements. It integrates three synchronous switching converters, two protected switched outputs, and an LDO to generate six independent power rails.
The device features a zero-loss PowerPath topology that allows each converter to run directly from either of two input power sources (USB or battery), ensuring seamless transitions without output interruptions. It supports a wide input voltage range from 1.8V to 5.5V, accommodating various battery chemistries including alkaline, NiMH, and Li-Ion.
The device supports an input voltage range from 1.8V to 5.5V.
The converter can supply a load of up to 800mA when the input voltage is 3.0V or greater.
The entire power supply, including all external components, occupies a PCB area of less than 3cm².
