Product Summary

The TNY268PN is an Enhanced, Energy Efficient, Low Power Off-line Switcher. The TNY268PN 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 TNY268PN incorporates auto-restart, line undervoltage sense, and frequency jittering. 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.

Parametrics

TNY268PN absolute maximum ratings: (1)DRAIN Voltage: -0.3 V to 700 V; (2)DRAIN Peak Current: 880 mA; (3)EN/UV Voltage: -0.3 V to 9 V; (4)EN/UV Current: 100 mA; (5)BYPASS Voltage: -0.3 V to 9 V; (6)Storage Temperature: -65 to 150℃; (7)Operating Junction Temperature: -40 to 150℃; (8)Lead Temperature: 260℃.

Features

TNY268PN features: (1)Fully integrated auto-restart for short circuit and open loop fault protection – saves external component costs; (2)Built-in circuitry practically eliminates audible noise with ordinary dip-varnished transformer; (3)Programmable line undervoltage detect feature prevents power on/off glitches – saves external components; (4)Frequency jittering dramatically reduces EMI (~10 dB) – minimizes EMI fi lter component costs; (5)132 kHz operation reduces transformer size – allows use of EF12.6 or EE13 cores for low cost and small size; (6)Very tight tolerances and negligible temperature variation on key parameters eases design and lowers cost; (7)Lowest component count switcher solution; (8)Expanded scalable device family for low system cost.
