FSQ0270RNA - Green Mode Fairchild Power Switch

Download the FSQ0270RNA datasheet PDF. This datasheet also covers the FSQ0170RNA variant, as both devices belong to the same green mode fairchild power switch family and are provided as variant models within a single manufacturer datasheet.

General Description

The FSQ0170RNA, and FSQ0270RNA, consists of an integrated current mode Pulse Width Modulator (PWM) and an avalanche-rugged 700V Sense FET.

It is specifically designed for high-performance off-line Switch Mode Power Supplies (SMPS) with minimal external components.

Key Features

  • Internal Avalanche Rugged 700V SenseFET.
  • Consumes only 0.8W at 230 VAC & 0.5W Load with Burst-Mode Operation.
  • Precision Fixed Operating Frequency, 100kHz.
  • Internal Start-up Circuit and Built-in Soft-Start.
  • Pulse-by-Pulse Current Limiting and Auto-Restart Mode.
  • Over-Voltage Protection (OVP), Overload Protection (OLP), Internal Thermal Shutdown Function (TSD).
  • Under-Voltage Lockout (UVLO).
  • Low Operating Current (3mA).
  • Adjustable Peak Current Limit Appl.
