Product Highlights
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
