Power Factor Correction ICs

FA5696N

  • Status:Available

The FA5696N is a control IC for configuring a critical-mode power factor correction converter. It achieves low power consumption by using a high-voltage CMOS process. It also has a redundant overvoltage protection function and output short-circuit protection circuit.

Features

  • Capable of low standby power by disabling input voltage detection
  • High-precision current detection: 0.6 V ± 5%
  • Improves efficiency under light loads using a maximum frequency limiting function
  • Prevents noise using a soft start and dynamic OVP circuit
  • Achieves low power consumption by using a high-voltage CMOS
    1. Startup of 80 μA (max), 2 mA (typ) during operation
  • Capable of directly driving power MOSFET, output peak current: source 1 A/sink 1 A
  • Stops switching and protects output even when an abnormality occurs in the output voltage detection line by separating the FB pin and overvoltage detection pin
  • Stops switching even when an abnormality occurs in the output voltage detection line using an FB short-circuit detection circuit
  • Built-in low voltage malfunction prevention circuit (9.6 V ON/9 V OFF)
  • Standby function
  • Package: SOP-8

Applications

  • Switching Power Supplies
