Negative charge pump

A negative charge pump is disclosed. The negative charge pump may be used to drive white LEDs in one application. The negative charge pump uses predominantly n-channel transistor switches that enables a smaller integrated circuit area. Further, a soft start mechanism is used in starting the charge p...
