Description

System interface supply voltage output and supply

voltage for companion controller circuit (40mA

maximum source capability). Requires a minimum of

two 0.1µF capacitors to ground for proper

decoupling.

Power supply source for main voltage converter

circuit. A 10µF and a 0.1µF ceramic capacitor must

be connected to this pin.

Connection to 10µH inductor for internal step up

converter. Note: inductor must be rated for 400mA

maximum peak current.

Intermediate output of main converter circuit.

Requires an external 4.7µF low ESR filter capacitor

to GND.

Ground.
