NCP7662 Datasheet (ON Semiconductor) - INDUCTORLESS VOLTAGE CONVERTER

NCP7662, INDUCTORLESS VOLTAGE CONVERTER

The NCP7662 contains all the necessary circuitry to complete a negative voltage converter, with the exception of two external capacitors which may be inexpensive 1 µF polarized electrolytic types.

The mode of operation of the device may be best understood by considering Figure 2, which shows an idea

NCP7662 Inductorless Voltage Converter The NCP7662 is a pin compatible upgrade to the industry standard TC7660 charge pump voltage converter.

It converts a +1.5 V to +15 V input to a corresponding 1.5 to 15 V output using only two low cost capacitors, eliminating inductors and their associated cost, size and EMI.

The on board oscillator operates at a nominal frequency of 10 kHz.

Frequency is increased to 35 kHz when pin 1 is connected to V+, allowing the
