  • Pin-out simplifies heat sinking to the PCB
  • SOURCE pins are electrically quiet for low EMI

TNY286PG belongs to TinySwitch-4 Family from the manufacturer "Power Integrations". It is Energy-Efficient, Off-Line Switcher with Line Compensated Overload Power. It comes with following features

The TYN266PN 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 Tiny Switch-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.
