TOP244YN

The TOP244YN is a TOPSwitch-GX EcoSmart integrated off line switcher in 6 pin TO-220 package. TOPSwitch-GX uses same proven topology as TOPSwitch 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 TOP244YN 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.
