Circuit
–
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.
