SC4809B - High Performance Current Mode PWM Controller

Download the SC4809B datasheet PDF. This datasheet also covers the SC4809A variant, as both devices belong to the same high performance current mode pwm controller family and are provided as variant models within a single manufacturer datasheet.

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.
