SC1660
SC1660 is SWITCHED CAPACITOR VOLTAGE CONVERTER manufactured by SEMTECH.
DESCRIPTION
The SC1660 is a monolithic CMOS switched capacitor voltage converter. Designed to be an improved direct replacement for the popular 7660, the SC1660 provides performance superior to previous designs by bining low quiescent current with high efficiency, and by eliminating diode drop voltage losses. The only required external ponents are two low cost electrolytic capacitors.
Features
- Improved direct replacement for 7660
- Easy to use
- 1.5V to 9V operation
- No external diode required
- Simple conversion of +5V to ±5V
- Low quiescent current
- High power efficiency
- Boost pin for higher switching frequency
