SC4806 - Multiple Function Double Ended PWM Controller

General Description

The SC4806 is a double ended, high speed, highly integrated PWM controller optimized for applications requiring minimum space.

Key Features

  • a programmable frequency up to 1MHZ, external www. DataSheet4U. com programmable soft start, pulse-by-pulse current limit and over current protection for both voltage and current modes, as well as a line monitoring input with hysteresis to reduce stress on the power components. A ramp pin allows for slope compensation to be programmed by external resistors for current mode. This also allows for operation in voltage mode with voltage feed forward. A unique oscillator is utilized which allows two SC.

Double Ended PWM Controller POWER MANAGEMENT Description The SC4806 is a double ended, high speed, highly integrated PWM controller optimized for applications requiring minimum space. The device is easily configurable for current mode or voltage mode operation and contains all the control circuitry required for isolated applications, where a secondary side error amplifier is used. Designed for simplicity, the SC4806 is fully featured and requires only a few external components. It features a programmable frequency up to 1MHZ, external www.DataSheet4U.com programmable soft start, pulse-by-pulse current limit and over current protection for both voltage and current modes, as well as a line monitoring input with hysteresis to reduce stress on the power components.
