TOP249FN Datasheet - Power Integrations

TOP249FN Integrated Off-line Switcher

TOPSwitch-GX uses the same proven topology as TOPSwitch, cost effectively integrating the 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 and improve design ﬂexibility, performance a.

TOP249FN Features

* eliminate or reduce cost of external components

* Fully integrated soft-start for minimum stress/overshoot

* Externally programmable accurate current limit

* Wider duty cycle for more power, smaller input capacitor

* Separate line sense and current limit pins on Y/R/F
