詳細說明

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. Compared to a discrete MOSFET and a PWM controller or an RCCsolution, a Fairchild Power Switch(FPS) can reduce the total component count, design size and weight and at the same time increase efficiency, productivity, and system reliability. It has a basic platform well suited for the cost effective design in a flyback converter.Features • Precision Fixed Operating Frequency (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

常見問題解答

What is KA5L0565R?

The KA5L0565R is a power switch mode PWM controller IC designed by Fairchild Semiconductor. It is commonly used in power supply applications such as AC-DC adapters, open frame power supplies, and LED drivers.

How Does KA5L0565R Work?

The KA5L0565R operates by controlling the power switch in a switching power supply. It utilizes pulse width modulation (PWM) to regulate the output voltage and current, providing efficient power conversion. The IC features built-in high-voltage startup and auto-restart functions for enhanced safety and reliability.

How Many Pins does KA5L0565R have and What are the Functions of the Pinout Configuration?

The KA5L0565R is housed in a 8-pin DIP (Dual Inline Package) or 8-pin SOP (Small Outline Package) package. The pinout configuration includes:

  • VCC: Power supply pin.
  • GND: Ground pin.
  • FB: Feedback pin for output voltage regulation.
  • CS: Current sense input for overcurrent protection.
  • SS: Soft start pin for controlling the startup time.
  • SYNC: Synchronization input for frequency synchronization.
  • RT: External resistor connection for setting the oscillator frequency.
  • DRV: Gate driver output for power MOSFET control.
