TOPSwitch-GX Family

Extended Power, Design Flexible,

EcoSmart, IntegratedOff-line Switcher

Product Highlights

OUT

Lower System Cost, High Design Flexibility

•

Extended power range for higher power applications

No heatsink required up to 34 W using P/G packages

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

)

Figure 1. Typical Flyback Application.

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

132 kHz frequency reduces transformer/power supply size

Half frequency option inY/R/F packages for video applications

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

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

the TOPSwitch standard DRAIN, SOURCE and CONTROL

terminals 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:

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

PWM gain) have tighter temperature and absolute tolerances

to simplify design and optimize system cost.
