Manufacturer: Fairchild (now onsemi)

Overview: .. .fairchildsemi. FSCQ-Series FSCQ0565RT / FSCQ0765RT / FSCQ0965RT / FSCQ1265RT FSCQ1465RT / FSCQ1565RT / FSCQ1565RP Green Mode Fairchild Power Switch.

General Description

In general, a Quasi-Resonant Converter (QRC) shows lower EMI and higher power conversion efficiency pared to conventional hard-switched converter with a fixed switching frequency.

Therefore, a QRC is well suited for noisesensitive applications, such as color TV and audio.

Each product in the FSCQ-Series contains an integrated Pulse Width Modulation (PWM) controller and a SenseFET, and is specifically designed for quasi-resonant off-line Switch Mode Power Supplies (SMPS) with minimal external ponents.

Key Features

  • Optimized for Quasi-Resonant Converter (QRC).
  • Advanced Burst-Mode Operation for under 1W Standby Power Consumption.
  • Pulse-by-Pulse Current Limit.
  • Over Load Protection (OLP) - Auto Restart.
  • Over Voltage Protection (OVP) - Auto Restart.
  • Abnormal Over Current Protection (AOCP) - Latch.
  • Internal Thermal Shutdown (TSD) - Latch.
  • Under Voltage Lock Out (UVLO) with Hysteresis.
  • Low Startup Current (typical : 25uA).
