{238} TNY266PN SMPS Have No Output Voltage / Switch Mode Power Supply IC Not Switching, Urdu Hindi

TNY266PN SMPS Switch Mode Power Supply Have No Output Voltage / IC Not Switching, How to Fix no power problem. i explained in urdu hindi language. TNY263P, TNY263G, TNY264P, TNY264G, TNY265P, TNY265G, TNY266P, TNY266G, TNY267P, TNY267G, TNY268P & TNY268G are TinySwitch-II family offline switching smps ICs to drive flyback toplogy, its switching frequency is 132KHz. Features it Reduces System Cost becasue it uses very minimal components to design the switch mode power supply. these are 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 less than 50 mW with bias winding and less than 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 Description TinySwitch™-II integrates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit and thermal shutdown circuitry onto a monolithic device. The start-up and operating power are derived directly from the voltage on thenDRAIN pin, eliminating the need for a bias winding and associated circuitry. In addition, the TinySwitch-II devices incorporate auto-restart, line undervoltage sense, and frequency jittering. An innovative design minimizes audio frequency components in the simple ON/OFF control scheme to practically eliminate audible noise with standard taped/varnished transformer construction. The fully integrated auto-restart circuit safely limits output power during fault conditions such as output short circuit or open loop, reducing component count and secondary feedback circuitry cost. An optional line sense resistor externally programs a line undervoltage threshold, which eliminates power down glitches caused by the slow discharge of input storage capacitors present in applications such as standby supplies. The operating frequency of 132 kHz is jittered to significantly reduce both the quasi-peak and average EMI, minimizing filtering cost.
