TOP256YN TOP256 TO-220 Transistor Bangladesh
AC/DC Switching Converters Int Off-Line Switchr 86W/119W
Low Cost Replacement for Discrete Switchers
• 20 to 50 fewer components – cuts cost, increases reliability
• Source-connected tab and Controlled MOSFET turn-on
reduce EMI and EMI filter costs
• Allows for a 50% smaller and lighter solution
• Cost competitive with linears above 5 W
Up to 90% Efficiency in Flyback Topology
• Built-in start-up and current limit reduce DC losses
• Low capacitance 700 V MOSFET cuts AC losses
• CMOS controller/gate driver consumes only 6 mW
• 70% maximum duty cycle minimizes conduction loss
Power Integrationsâ€™ TOPSwitchÂ®-HX device cost-effectively incorporates a 700V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection, and other control circuitry onto a monolithic device. The integrated off-line switcher features Power Integrationsâ€™ EcoSmartÂ® technology that enables power consumption of less than 200mW at no load and maintains constant efficiency over the full line and load range. The TOPSwitch-HX family meets efficiency requirements for the new energy-efficient standards and enables the design of compact and cost-effective switching power supplies.
