POWER INTEGRATIONS TOP247YN Datasheet & Stock

The TOP247YN is a TOPSwitch-GX EcoSmart integrated off line switcher in 6 pin TO-220 package. TOPSwitch-GX uses same proven topology as TOPSwitch which cost effectively by integrating high voltage power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip. Many new functions are integrated to reduce system cost, improve design flexibility, high performance and energy efficient. The TOP247YN features soft start, frequency jittering for lower EMI, wider DCMAX, hysteretic thermal shutdown and larger creepage packages. In addition all critical parameters (current limit, frequency, PWM gain) have tighter temperature and absolute tolerances to simplify design and optimize system cost.




Output power of 165W at 230VAC and 125W at 85VAC to 265VAC in open frame design

Output power of 85W at 230VAC and 55W at 85VAC to 265VAC in non ventilated enclosed adapter

Extended power range for higher power applications

Wider duty cycle for more power, smaller input capacitor

Regulates to zero load without dummy loading

132KHz frequency reduces transformer/power supply size

Hysteretic thermal shutdown for automatic fault recovery
