SCM1710A - Highly Integrated PWMController

General Description

This highly integrated SCM1710A current model PWM controller is ideal for offline AC-DC converter designs.

The chip’s accurate operating frequency is achieved by trimming, its maximum switching frequency can be set by means of external resistor values.

Key Features

  • Maximum operating frequency is adjustable.
  • Input undervoltage protection.
  • Built-in compensation for opto-coupler.
  • Compensation for prefeedback.
  • Cycle-by-cycle current limit, overcurrent protection.
  • Amplitude and frequency reduction under light load condition.
  • Soft startup.
  • VDD overvoltage protection and undervoltage lockout.
  • Open loop and CS pin floating protection.
  • RI pin short circuit protection.
  • Input undervoltage protection.
