NCP3163

3.4 A, Step−Up/Down/

Inverting 50−300 kHz

Switching Regulator

The NCP3163 Series is a performance enhancement to the popular

MC33163 and MC34163 monolithic DC−DC converters. These

devices consist of an internal temperature compensated reference,

comparator, controlled duty cycle oscillator with an active current

limit circuit, driver and high current output switch. This controller was

specifically designed to be incorporated in step−down, step−up, or

voltage−inverting applications with a minimum number of external

components. The NCP3163 comes in an exposed pad package which

can greatly increase the power dissipation of the built in power switch.
