This datasheet also covers the TOP247F variant, as both devices belong to the same integrated off-line switcher family and are provided as variant models within a single manufacturer datasheet.
General Description
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.
Key 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 packages.
Line under-voltage (UV) detection: no turn off glitches.
Line overvoltage (OV) shutdown extends line surge limit.
