Product Details

The LinkSwitch-HP family of flyback power supply ICs incorporate a primary side regulated (PSR) controller and high-voltage power MOSFET in a single package. The IC family includes devices optimized for constant voltage (CV) operation at power ranges from 9W to 90 W. LinkSwitch-HP IC controller features +/-5% CV accuracy, selectable current limit, programmable latching or hysteretic OVP, UVP and OTP, improved overload power compensation over line, fast AC reset, and programmable shutdown delay time.

Product Highlights

EcoSmart - Energy Efficient

  • Multi-mode control maximizes efficiency over full load range
  • No-load consumption below 30 mW at 230 VAC
  • >75% efficiency with 1 W input at 230 VAC
  • >50% efficiency with 0.1 W input at 230 VAC

High Design Flexibility for Low System Cost

  • Dramatically simplifies power supply designs
  • 132 kHz operation reduces transformer and power supply size
  • Accurate programmable current limit
  • Frequency jittering reduces EMI filter cost
  • Fully integrated soft-start for minimum start-up stress
  • 725 V MOSFET simplifies meeting derating requirements (LNK677x)
  • 650 V MOSFET for lowest system cost (LNK676x/LNK666x)
  • Fast transient response family option (LNK666x)

Extensive Protection Features

  • Output short-circuit protection (SCP)
  • Ouput overload/over-current protection (OPP, OCP)
  • Optional extended shutdown delay time
  • Output overvoltage protection (OVP), hysteretic or latching
  • Line brown-in/out protection (line UV)
  • Line overvoltage (OV) shutdown extends line surge withstand
  • Accurate thermal shutdown (OTP), hysteretic or latching

Advanced Green Package Options

  • eSIP-7C package:
    • Vertical orientation for minimum PCB footprint
    • Simple heat sink mounting using clip or adhesive pad
  • eSOP-12B package:
    • Low profile surface mounted for ultra-slim designs
    • Heat transfer to PCB via exposed pad and SOURCE pins
    • Supports either wave or IR reflow soldering
  • eDIP-12B package:
    • Low profile through-hole mounted for ultra-slim designs
    • Heat transfer to PCB via exposed pad or optional metal heat sink
  • Extended creepage to DRAIN pin
  • Heat sink is connected to SOURCE for low EMI
  • Halogen free and RoHS compliant
