Manufacturer: Fairchild (now onsemi)

Overview: www.fairchildsemi.com KA5x03xx-SERIES KA5H0365R, KA5M0365R, KA5L0365R KA5H0380R, KA5M0380R, KA5L0380R Fairchild Power.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The Fairchild Power Switch(FPS) product family is specially designed for an off-line SMPS with minimal external components.

The Fairchild Power Switch(FPS) consists of a high voltage power SenseFET and a current mode PWM IC.

Included PWM controller integrates the fixed frequency oscillator, the under voltage lock-out, the leading edge blanking, the optimized gate turn-on/turn-off driver, the thermal shutdown protection, the over voltage protection, and the temperature compensated precision current sources for the loop compensation and the fault protection circuitry.

Key Features

  • Precision Fixed Operating Frequency (100/67/50kHz).
  • Low Start-up Current(Typ. 100uA).
  • Pulse by Pulse Current Limiting.
  • Over Current Protection.
  • Over Voltage Protection (Min. 25V).
  • Internal Thermal Shutdown Function.
  • Under Voltage Lockout.
  • Internal High Voltage Sense FET.
  • Auto-Restart Mode.
