Description

The NCP7662 is a pincompatible upgrade to the industry standard TC7660 charge pump voltage converter. NCP7662 converts a +1.5 V to +15 V input to a corresponding 1.5 to 15 V output using only two lowcost capacitors, eliminating inductors and their associated cost, size and EMI.

The onboard oscillator operates at a nominal frequency of 10 kHz. Frequency is increased to 35 kHz when pin 1 is connected to V+, allowing the use of smaller external capacitors. Operation below 10 kHz (for lower supply current applications) is also possible by connecting an external capacitor from OSC to ground (with pin 1 open).The NCP7662 is available in both 8pin DIP and 8pin small outline (SO) packages in commercial and extended temperature ranges.
