SP6660DS/11

SP6660 200mA Charge Pump Inverter or Doubler

PIN ASSIGNMENTS

Pin 1— FC — Frequency Control for the

internal oscillator. FC = open,f

OS C = 10KHz

typical; FC = V+, f

OSC = 80KHz typical

Pin 2 — CAP+ — Connect to the positive

terminal of the charge pump capacitor.

Pin 3 — GND — (Voltage Inverter Circuit)

Ground.

Pin 3 — GND — (Positive Voltage Doubler

Circuit) Positive supply voltage input.

Pin 4 — CAP- — Connect to the negative

terminal of the charge pump capacitor.

Pin 5 — OUT — (Voltage Inverter Circuit)

Negative voltage output pin.

Pin 5 — OUT — (Positive Voltage Doubler

Circuit) Ground pin for power supply.

Pin 6 — LV

Low-voltage operation input pin in 660

circuits. In SP6660 circuits can be connected

to GND, OUT or left open as desired with no

effect.

Pin 7 — OSC — Control pin for the oscillator.

Internally connected to 15pf capacitor.

An external capacitor can be added to slow

the oscillator. Be careful to minimize stray

capitance. An external oscillator can be

connected to overdrive the OSC pin.

Pin 8 — V+ — (Voltage Inverter Circuit)

Positive voltage input pin for the power

supply.

Pin 8 — V+ — (Positive Voltage Doubler

Circuit) Positive voltage output.
