TNY266PN IC-Power Integrations Off Line Switcher IC

TNY266PN IC-Power Integrations Off Line Switcher 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:

• BYPASS Pin Voltage: 5.6 ~ 6.15V
• BYPASS Pin Voltage Hysteresis: 0.8 ~ 1.2V
• Leading Edge Blanking Time: 170 ~ 215 ns
• Fully integrated auto-restart for short circuit and open loop fault protection – saves external component costs
• Built-in circuitry practically eliminates audible noise with an ordinary dip-varnished transformer
• Programmable line under-voltage detect feature prevents power on/off glitches – saves external components
• Frequency jittering dramatically reduces EMI (~10 dB)– minimizes EMI filter component costs
• 132 kHz operation reduces transformer size – allows the use of EF12.6 or EE13 cores for low cost and small size
• Very tight tolerances and negligible temperature variation on key parameters eases design and lowers the cost
• Lowest component count switcher solution
• Expanded scalable device family for low system cost
• Thermal Shutdown Temperature: 125 ~ 150°C
• Thermal Shutdown Hysteresis: 70°C

Package Includes:

• 1 x TNY266PN IC-Power Integrations Off-Line Switcher IC
