Product Highlights
Lower System Cost, High Design Flexibility
Extended power range to 290 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
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 (DC
MAX)
reduction rejects line ripple and limits DC
MAX 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 re-
duce system cost and improve design flexibility, performance
and energy efficiency.
Depending on package type, the TOPSwitch-GX family has
either 1 or 3 additional pins over the standard DRAIN, SOURCE
and CONTROL terminals allowing the following functions: line
sensing (OV/UV, line feedforward/DC max reduction), accu-
rate externally set current limit, remote on/off, and synchroni-
zation 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.
