NCV3064
1.5 A, Step-Up/Down/
Inverting Switching
Regulator with ON/OFF
Function
MC33063A and MC34063A 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 series was
specifically designed to be incorporated in Step−Down and Step−Up
and Voltage−Inverting applications with a minimum number of
external components. The ON/OFF pin provides a low power
shutdown mode.
