FSQ0370RLA - Green Mode Fairchild Power Switch

Download the FSQ0370RLA datasheet PDF. This datasheet also covers the FSQ0370RNA 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 FSQ0370 consists of an integrated Current Mode Pulse Width Modulator (PWM) and an avalanche rugged 700V SenseFET.

It is specifically designed for highperformance offline Switched Mode Power Supplies (SMPS) with minimal external components.

Key Features

  • Internal Avalanche Rugged 700V SenseFET.
  • Consumes Only 0.8W at 230VAC & 0.5W Load with Burst-Mode Operation.
  • Precision Fixed Operating Frequency: 100kHz.
  • Internal Startup Circuit and Built-in Soft-Start.
  • Pulse-by-Pulse Current Limiting, 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 Applicatio.
