PIN DESCRIPTIONS
PIN 1:VOUT -
Regulated output voltage. For the
best performance, V_OUT should be
bypassed with a 2.2µF (min) low
ESR capacitor with the shortest
distance in between.
PIN 2: GND - Ground. Should be tied to a
ground plane for best performance.
PIN 3: SHDN - Active low shutdown input. A low
voltage on SHDN disables the
AIC1845. SHDN is not allowed to
float.
PIN 4: C- - Flying capacitor negative terminal.
PIN 5: VIN - Input supply voltage. V_IN should
be bypassed with a 2.2µF (min)
low ESR capacitor.
PIN 6: C+ - Flying capacitor positive terminal.
