TOP247YN

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 34 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 at 110 VAC, 160 mW at 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 thermal shutdown, and larger creepage packages. In 
addition, all critical parameters (i.e. current limit, frequency, 
PWM gain) have tighter temperature and absolute tolerances 
to  simplify design and optimize system cost.
