TOPSwitch -GX Family

Extended Power, Design Flexible,

EcoSmart^®, IntegratedOff-line Switcher

Product Highlights

Lower System Cost, High Design Flexibility

OUT

• Extended power range to 250 W

• 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

CONTROL

• Separate line sense and current limit pins on Y/R packages

• Line under-voltage (UV) detection: no turn off glitches

• Line overvoltage (OV) shutdown extends line surge limit

TOPSwitch-GX

• Line feed forward with maximum duty cycle (DC_MAX

reduction rejects line ripple and limits DC_MAXat high line

• Frequency jittering reduces EMI and EMI filtering costs

• Regulates to zero load without dummy loading

)

PI-2632-060200

• 132 kHz frequency reduces transformer/power supply size

• HalffrequencyoptioninY/Rpackagesforvideoapplications

• Hysteretic thermal shutdown for automatic fault recovery

• Large thermal hysteresis prevents PC board overheating

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

and energy efficiency.

addition, all critical parameters (i.e. current limit, frequency,

PWM gain) have tighter temperature and absolute tolerance, to

simplify design and optimize system cost.
