Description

The G5130/G5131 boost converter is designed for use of main power source on portable equipments.

G5131 consist of an oscillator, PSM control logic circuit, an embedded power MOS (LX switch), accurate voltage reference, error amplifier, feedback resistors, and LX protection circuit. 

Only 3 external components (includes 1 inductor, 1 diode and 1 capacitor) of G5131 are needed to construct the power application.

For larger output power application, G5131 can be used to drive an external NPN device for more input current.
