TinySwitch-II Features Reduce System Cost
• Fully integrated auto-restart for short circuit and open loop fault
protection – saves external component costs
• Built-in circuitry practically eliminates audible noise with ordinary
dip-varnished transformer
• Programmable line undervoltage detect feature prevents power
on/off glitches – saves external components
• Frequency jittering dramatically reduces EMI (~10 dB)
– minimizes EMI filter component costs
• 132 kHz operation reduces transformer size – allows use of
EF12.6 or EE13 cores for low cost and small size
• Very tight tolerances and negligible temperature variation on key
parameters eases design and lowers cost
• Lowest component count switcher solution
• Expanded scalable device family for low system cost
Better Cost/Performance over RCC & Linears
• Lower system cost than RCC, discrete PWM and other
integrated/hybrid solutions
• Cost effective replacement for bulky regulated linears
• Simple ON/OFF control – no loop compensation needed
• No bias winding – simpler, lower cost transformer
• Simple design practically eliminates rework in manufacturing
EcoSmart™– Extremely Energy Efficient
• No load consumption <50 mW with bias winding and
<250 mW without bias winding at 265 VAC input
• Meets California Energy Commission (CEC), Energy Star, and
EU requirements
• Ideal for cell-phone charger and PC standby applications
High Performance at Low Cost
• High voltage powered – ideal for charger applications
• High bandwidth provides fast turn on with no overshoot
• Current limit operation rejects line frequency ripple
• Built-in current limit and thermal protection improves safety
