General Description

The CA1523 monolithic silicon integrated circuit is a variable interval pulse regulator designed to provide the control circuitry for use in switching regulator circuits.

It operates from 11V to 15V.

The regulator provides a single output drive capable of 300mA source/200mA sink.

Key Features

  • Operates up to 200kHz.
  • Pins ESD Protected.
  • Remote ON/OFF.
  • Slow Start with Reset.
  • Overcurrent Sensing.
  • Lower Peak Currents than PWM Regulator - Less Prone to Magnetic Saturation.
