Description The MC34063A/MC33063A is a monolithic regulator subsystem intended for a DC to DC converter. The device contains a temperature-compensated bandgap reference, a duty cycle control oscillator, driver, and high-current output switch. It can be used for stepdown, step-up, or inverting switching and series pass regulators. Features ■ Operation from 3.0 to 40V Input ■ Short Circuit Current Limiting ■ Low Standby Current ■ Output Switch Current of 1.5A Without External Transistors ■ Adjustable Output Voltage ■ Frequency of Operation from 100Hz to 100KHz ■ Step-up, Step Down, or Inverting Switching Regulators
