T0P248, T0P243 Datasheet (Power Integrations) - Integrated Off-line Switcher

T0P248, T0P243, 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

T0P248 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 p
