FS6X1220R

Fairchild Power Switch (FPS )

Features

Description

• Current Mode PWM Control With a Fixed Operating

Frequency (300kHz)

The FS6X1220R is specially designed for an off-line DC-

DC converters with minimal external components. This

device is a current mode PWM controller combined with a high

voltage power SenseFET in a single package. The PWM

controller includes integrated fixed frequency oscillator, line

under voltage lockout, sleep on/off function, thermal

shutdown protection, over voltage protection, pulse-by-pulse

current limit and temperature compensated precise current

sources for a loop compensation. Compared with discrete

MOSFET and PWM controller solution, the FS6X1220R can

reduce total cost, component count, size and weight simulta-

neously increasing efficiency, productivity, and system

reliability. This device is well suited for DC to DC converter

applications up to 40W of output power.

• Pulse by Pulse Current Limit

• Over Load Protection

• Over Voltage Protection

• Thermal Shutdown

• Built-in Auto-Restart Circuit

• Line Under Voltage Detection and Sleep on/off Function

• Internal High Voltage SenseFET (QFET)

• Supports Forward or Flyback Topology

Application

• DC-DC Converter
