TOPSwitch®-GX Family
Extended Power, Design Flexible,
EcoSmart,® Integrated Off-line Switcher
Product Highlights
Lower System Cost, High Design Flexibility
• 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
• Line feed forward with maximum duty cycle (DCMAX)
reduction rejects line ripple and limits DCMAX at 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 in Y/R/F packages for video applications
• Hysteretic thermal shutdown for automatic fault recovery
• Large thermal hysteresis prevents PC board overheating
EcoSmart - Energy Efficient
• Extremely low consumption in remote off mode
(80 mW @ 110 VAC, 160 mW @ 230 VAC)
• Frequency lowered with load for high standby efficiency
• Allows shutdown/wake-up via LAN/input port
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 CONTROL terminals
allow the following functions: line sensing (OV/UV, line feed-
forward/DCMAX reduction), 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 DCMAX, hysteretic

tighter temperature and absolute tolerance, to simplify design and
optimize system cost.
