NCP7662
Inductorless Voltage
Converter
The NCP7662 is a pin鈥揷ompatible upgrade to the industry standard
TC7660 charge pump voltage converter. It converts a +1.5 V to +15 V
input to a corresponding 鈥?.5 to 鈥?5 V output using only two low鈥揷ost
capacitors, eliminating inductors and their associated cost, size and
EMI.
The on鈥揵oard 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 8鈥損in DIP and 8鈥損in small outline
(SO) packages in commercial and extended temperature ranges.
