TNY266PN Off-line Switcher

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 the DRAIN 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.

Features :

TinySwitch-II Features Reduce System Cost

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 filter 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
