Product Description

The TOP246YN 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 TOP246YN 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 125W at 230VAC and 90W at 85VAC to 265VAC in open frame design
Output power of 60W at 230VAC and 40W 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
Large thermal hysteresis prevents PC board overheating
Switching frequency of 132KHz (frequency pin connected to source) and 66KHz (connected to control)
Operating junction temperature range from -40°C to 150°C
