Datasheet Summary
SGM3804 Single Inductor, Positive/Negative Dual Output, Buck/Boost Converter
GENERAL DESCRIPTION
The SGM3804 generates both positive and negative precision regulated voltage power sources, with a patent pending control scheme for single inductor dual output converter. Outputs are programmable in 100mV steps in 2.4V to 6.4V range, which are monly used in drivers for LCD displays and AMOLED displays, as well as in any other circuits requiring both rails, with different loading on each rail. The device is equipped with I2C interface. With input in the range of 2.7V to 5.5V, the device is optimized for loading 100mA in boost-inverter mode and also works in buck-inverter mode.
