TNY268PN IC-Power Integrations Off Line Switcher with Low Power IC

TNY268PN IC-Power Integrations Off-Line Switcher with Low Power IC

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.

Features/Specs:

1. TinySwitch-II Features Reduce System Cost
 • 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 undervolt
2. Better Cost/Performance over RCC & Linears
 • Lower system cost than RCC, discrete PWM, and other integrated/hybrid solutions
 • Cost-effective replacement for bulky regulated linear
 • Simple ON/OFF control – no loop compensation needed
3. EcoSmart™– Extremely Energy Efficient
 • No-load consumption <50 mW with bias winding and <250 mW without bias winding at 265 VAC input
4. High Performance at Low Cost
 • High voltage powered – ideal for charger applications
 • High bandwidth provides fast turn on with no overshoot

Package Includes:

• 1 x TNY268PN IC-Power Integrations Off-Line Switcher with Low Power IC
