Description
LinkSwitch-HF integrates a 700 V power MOSFET, oscillator, simple ON/OFF control scheme, a high voltage switched current
source, frequency jittering, cycle-by-cycle current limit, and thermal shutdown circuitry onto a monolithic IC.The start-up and operating power are derived directly from the DRAIN pin, eliminating the need for a bias winding and associated circuitry.The 200 kHz maximum switching frequency allows very low flux transformer designs, practically eliminating audible noise with th
Features
- Optimized for Lowest System Cost.
- Fully integrated auto-restart for short-circuit and open loop protection.
- Self-biased supply.
- saves transformer auxiliary winding and associated bias supply components.
- Tight tolerances and negligible temperature variation on key parameters eases design and lowers cost.
- High maximum switching frequency allows very low flux density transformer designs, practically eliminating audible noise.
- Frequency jittering.
