SCM1702A - CC/CV Primary-Side Regulator

General Description

SCM1702A is a flyback primary side power supply controller.

It provides isolated Constant Voltage (CV) and Constant Current (CC) output without using an opto-coupler.

Key Features

  • Primary-side regulation eliminates optocoupler.
  • Built-in loop compensation.
  • Built-in 650V start-up switch.
  • Built-in 650Vpower MOSFET.
  • Programmable cable compensation (CBC).
  • Output rectifier forward drop temperature variations compensation.
  • Wide VDD range allows small bias capacitor.
  • Large capacitive loading with self-power at start-up state.
  • Over-voltage, over-temperature and over-current protection.
  • FB pin and CS pin fault protection Applicatio.
