Overview
SGM3803 90% Efficient Synchronous Step-Up Converter with 200mA Negative Charge Pump Inverter GENERAL DESCRIPTION The SGM3803 is a constant frequency, current mode, synchronous step-up switching regulator with 200mA negative charge pump inverter which generates an unregulated negative output voltage from an input voltage ranging from 1.
4V to 5.
5V.
The device is typically used to generate +5V and -5V from battery.
High switching frequency minimizes the sizes of inductor and capacitor.
Only three external capacitors are required to build a complete charge pump inverter.
Integrated power MOSFETs and internal compensation of boost DC/DC make the SGM3803 simple to use and fit the total solution i...
