TinySwitch-II Family
Enhanced, Energy Efficient, Low Power Off-line Switcher
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 under-voltage 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
