FSDH0165D - Fairchild Power Switch

General Description

The FSDH0165D is specially designed for an off-line SMPS with minimal external components.

The FSDH0165D is a monolithic high voltage power switching regulator that combine the SenseFET(LDMOS) with voltage mode PWM control block.

Key Features

  • Single chip 650V 1A senseFET powerswitch Precision fixed operating frequency (100kHz) Internal start-up switch UVLO with hysteresis (6.7V/8.7V) Over load protection (typ. 4.5V) Over current protection (typ. 0.48A) Internal thermal shutdown function Secondary side regulation Auto-restart mode No load consumption < 250mW at 265VAC input.
