Description

The LM2661, LM2663, and LM2664 are part of a family of CMOS charge-pump voltage converters (Table 2). Each uses two small capacitors to achieve voltage inversion or voltage doubling without the cost, size, and EMI of inductor based converters. Each device has a shutdown feature and the LM2661 and LM2663 also provide the ability to run the clock oscillator from an external source. You may also slow the clock with an external capacitor on the LM2661 and LM2663. The small size and low profile of these circuits makes them attractive for cellular phones, laptop computers, Op Amp power supplies, interface power supplies, medical instruments, PDAs, and handheld instruments.
