TOP249YN – 265VAC to 12VDC AC to DC Off-Line Switcher – TO-220 Package
The TOP249YN is a TOPSwitch-GX EcoSmart integrated offline switcher in a 6-pin TO-220 package. TOPSwitch-GX uses the same proven topology as TOPSwitch which cost-effectively integrates 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 costs and improve design flexibility, high performance and energy efficiency. The TOP249YN features a 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.
