TOPSwitch-GX Family

Extended Power, Design Flexible,

EcoSmart, IntegratedOff-line Switcher

Product Highlights

Lower System Cost, High Design Flexibility

OUT

• Extended power range for higher power applications

• No heatsink required up to 30 W using P package

• 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

CONTROL

TOPSwitch-GX

PI-2632-060200

• 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

)

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. Many new functions are integrated to

reduce system cost and improve design flexibility, performance

and energy efficiency.

Depending on package type, either 1 or 3 additional pins over the

TOPSwitch standard DRAIN, SOURCE and CONTROLterminals

allow the following functions: line sensing (OV/UV, line feed-

forward/DC_MAXreduction), accurate externally set current limit,

remote ON/OFF, synchronization to an external lower frequency,

and frequency selection (132 kHz/66 kHz).

All package types provide the following transparent features: Soft-

start, 132 kHz switching frequency (automatically reduced at light

load), frequency jittering for lower EMI, wider DC_MAX, hysteretic

thermal shutdown and larger creepage packages. In addition, all

critical parameters (i.e. current limit, frequency, PWM gain) have

tighter temperature and absolute tolerance, to simplify design and

optimize system cost.

enclosed adapter measured at 50 °C ambient. 2. Maximum practical

continuous power in an open frame design at 50 °C ambient. See

Key Applications for detailed conditions. 3. See Part Ordering

Information. 4. 230 VAC or 100/115 VAC with doubler.
