FSDM1265RB Datasheet Green Mode Fairchild Power Switch

Manufacturer: Fairchild (now onsemi)

Overview: .fairchildsemi. FSDM1265RB.

General Description

The FSDM1265RB is an integrated Pulse-Width Modulator (PWM) and a SenseFET which is specifically designed for high performance offline SMPS with minimal external ponents.

This device is an integrated high-voltage power switching regulator which bines a rugged avalanche Sense FET with a current mode PWM control block.

The PWM controller includes integrated fixed frequency oscillator, under-voltage lockout, leading edge blanking (LEB), optimized gate driver, internal soft-start, and precise current sources that are temperature pensated for loop pensation and self protection circuitry.

Key Features

  • Green Mode Fairchild Power Switch (FPSTM).
  • Internal Avalanche Rugged Sense FET.
  • Advanced Burst-Mode operation that consumes less than 1 W at 240VAC and 0.5W load.
  • Precision Fixed Operating Frequency (66kHz).
  • Internal Start-up Circuit.
  • Improved Pulse by Pulse Current Limiting.
  • Over-Voltage Protection (OVP).
  • Over-Load Protection (OLP).
  • Internal Thermal Shutdown Function (TSD).
  • Auto-Restart Mode.
  • Under Voltag.
