Product Highlights
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
effi ciency
• 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
• Lowest component count switcher solution
Features Superior to Linear/RCC
• Accurate hysteretic thermal shutdown protection –
automatic recovery improves fi eld 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
EcoSmart®– Extremely Energy Effi cient
• Easily meets all global energy effi ciency regulations with
no added components
• No-load consumption <300 mW without bias winding at
265 VAC input (<50 mW with bias winding)
• ON/OFF control provides constant effi ciency to very
light loads – ideal for mandatory CEC regulations
Applications
• Chargers/adapters for cell/cordless phones, PDAs, digital
cameras, MP3/portable audio players, and shavers
• Supplies for appliances, industrial systems, and metering
