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
• Lowest component count switcher solution
Features Superior to 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
EcoSmart™– Extremely Energy-Efficient
• Easily meets all global energy efficiency 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 efficiency 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
