Product Summary

The TNY268PN is an enhanced, energy efficient, low power off-line switcher. It integrates a 700V 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. 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.

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 under-voltage detect feature prevents power on/off glitches-saves external components; (4)Frequency jittering dramatically reduces EMI (~10 dB): minimizes EMI filter component costs; (5)132 kHz operation reduces transformer size-allows use of EF12.6 or EE13 cores for low cost and small size.
