FSDH321 POWER SWITCH Description
It integrates Pulse width modulator and Field Effect Transistors as sensors. It is used as high voltage switching device. It contains a fixed oscillator. The fixed oscillator does frequency modulation for reducing electromagnetic interference. It also has under voltage lockout protection, leading edge blanking, optimized gate turn on/ off driver, thermal shutdown protection, abnormal over current protection and temperature compensated precision current sources for long compensation and fault protection circuitry along with Schmitt trigger. It comes in 8 DIP and 8 LSOP package.
FSDH321 Features
● It has following features
● It has feature for internal start up circuit.
● It has feature of pulse by pulse current limitation
● It has built in soft start
● It has auto restart mode
● It has low operating current typically 3milli Amperes
● It has adjustable peak current limit
● It has feature of advanced burst mode operation in which load will consume only 0.65watts at 240Volts AC supply.
