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