Description
This pin is switching output of boost converter.
Power supply pin
This pin is set by soft start for boost converter. Please
connect capacitor to GND for soft start time.
Analog ground of PMIC
This pin is input for LDO feedback.
This pin is output for LDO.
This pin is input supply for LDO.
This pin is input for detector.
This pin is output for detector. GIN is an open-drain output.
This pin is set by delay for detector. Please connect capacitor
to GND for delay time.
This pin is set by delay for gate slop start time.
This pin is input for gate slop timing.
This pin is controlled gate slop voltage by external
resistance.
This pin is output for gate slop.
This pin is input supply for gate slop circuit.
This pin is feedback input for positive charge pump.
This pin is output for positive charge pump.
This pin is input supply for operational amplifier, positive
charge pump.
This pin is output of operational amplifier.
This pin is the non-inverting input of operational amplifier.
