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
EcoSmartTM- 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
