Features

• LinkSwitch-HP series Offline AC-DC Converters. The Power Integrations LinkSwitch-HP family of flyback power supply ICs incorporate a primary side regulated controller and high-voltage power MOSFET in a single package. These devices feature ±5% CV accuracy, selectable current limit, programmable latching or hysteretic over-voltage, under-voltage and over-temperature protection, fast AC reset, and programmable shutdown delay time. Package options: ; eSIP-7C package for vertical orientation with minimum PCB footprint size and simple heat sink mounting using clip or adhesive pad ; eSOP-12B package for low-profile surface mounted ultra-thin designs with heat transfer to PCB via exposed pad and SOURCE pins; both wave and IR reflow soldering supported ; eDIP-12B package for low-profile through-hole mounted ultra-thin designs with heat transfer to PCB via exposed pad or optional metal heat sink. ; 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 ; Dramatically simplifies power supply designs ; Eliminates opto-coupler and all secondary control circuitry ; ±5% or better output voltage tolerance ; 132 kHz operation reduces transformer and power supply size ; Compensation over line limits overload power ; Frequency jittering reduces EMI filter cost ; Fully integrated soft-start for minimum start-up stress ; Auto-restart limits power delivery to 3% during overload faults
