3.4 A, StepUp/Down/
Inverting 50300 kHz
Switching Regulator
The NCP3163 Series is a performance enhancement to the popular
MC33163 and MC34163 monolithic DCDC 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 stepdown, stepup, or
voltageinverting 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.
