SC4809A - High Performance Current Mode PWM Controller

Description

The SC4809A/B/C is a 10 pin BICMOS primary side current mode controller for use in Isolated DC-DC and off-line switching power supplies.

It is a highly integrated solution, requiring few external components.

Features

  • a high frequency of operation, accurately programmable maximum duty cycle, current mode control, line voltage monitoring, supply UVLO, low start-up current, and programmable soft start with user accessible reference. It operates in a fixed frequency, highly desirable for www. DataSheet4U. com Telecom.
