this ic family is 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
Frequency jittering dramatically reduces EMI (~10 dB)
minimizes EMI filter component costs
132 kHz fix frequency operation reduces transformer size - allows use
of EF12.6 or EE13 cores
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
Lower system cost than RCC, discrete PWM and other integrated/hybrid solutions
it is 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
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 the DRAIN pin, eliminating the need for a bias winding and associated circuitry. In addition, the
Minimum continuous power in a typical non-ventilated enclosed adapter measured at 50 °C ambient.
Minimum practical continuous power in an open frame design with adequate heat sinking, measured at 50 °C ambient (See Key Applications Considerations).
Packages: P: DIP-8B, G: SMD-8B. For lead-free package options, see Part
Ordering Information.
TinySwitch-II devices incorporate auto-restart, line under voltage
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 under-voltage 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.

Sir, there is a ic named INN2604K used in O general inverter ac indoor unit pcb
Sir how does it work
Ek desktop psu hai us m standby pr TNY-378 lage hai. Start m voltage pore 5v atey hain. Ground se short kro supply on hojati hai leken jb motherboard connect kro tou standby voltage 4 hojate hain aur supply on nh hoti. 2nd supply se motherboard check kia hai woh thek hai. Kindly kch btaye kia issue hoskta hai
