General PWM-ICs

FA5510N

  • Status:Available

FA5510 is a PWM switching power supply control IC that can directly drive power MOSFETs. It uses a high-voltage CMOS (30 V withstand voltage) device to achieve low power consumption. In addition, despite its 8-pin package, it incorporates a wide variety of protective functions and reduces the number of external components, making it ideal for compact, high-performance, and high-efficiency power supplies that achieve power savings.

Features

  • Low current consumption by CMOS process with high dielectric strength (30V)
    1. Standby current of 2μA or less (at Vcc = 14V), and operating current of 1.5mA (typ)
  • Overvoltage protection function detecting the Vcc voltage
  • A drive circuit for connecting a power MOSFET directly
    1. Output peak current: ±1.5A
  • Pulse-by-pulse overcurrent limiting function
  • Overload protection function (latch or non-latch mode selectable)
  • Output ON-OFF function by external signal
  • Latch-mode overvoltage shutdown function
  • Undervoltage lockout function (16.5V ON / 9V OFF)
  • Reference voltage output (5V)
  • Maximum duty cycle 46%
  • Package: SOP-8

Applications

  • Switching Power Supplies
