Product Details
Description:
Optimized for Lowest System Cost
- Proprietary IC trimming and transformer construction techniques enable Clampless™ designs with LNK362 for lower system cost, component count and higher efficiency
- Fully integrated auto-restart for short circuit and open loop protection
- Self-biased supply – saves transformer auxiliary winding and associated bias supply components
- Frequency jittering greatly reduces EMI
- Meets HV creepage requirements between DRAIN and all other pins both on the PCB and at the package
Richer Feature Set than Linear/RCC
- Accurate hysteretic thermal shutdown protection – automatic recovery improves field reliability
- Universal input range allows worldwide operation
- Simple ON/OFF control, no loop compensation needed
- Eliminates bias winding – simpler, lower cost transformer
- Very low component count – higher reliability and single side printed circuit board
- Auto-restart reduces delivered power by 95% during short circuit and open loop fault conditions
- High bandwidth provides fast turn on with no overshoot and excellent transient load response
Applications:
- Chargers for cell/cordless phones, PDAs, digital cameras, MP3/portable audio players, and shavers
- Supplies for appliances, industrial systems, and metering
