Externally programmable accurate current limit

Wider duty cycle for more power, smaller input capacitor

Separate line sense and current limit pins on Y/R packages

Line under-voltage(UV) detection: no turn off glitches

Line over voltage(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

132kHz frequency reduces transformer/power supply size

Halffrequency option in Y/R packages for video applications

Hysteretic thermal shutdown for automatic fault recovery

Large thermal hysteresis prevents PC board overheating

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, 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), accurate externally set current limit, remote on/off, and synchronization to an external lower frequency and frequency selection (132 kHz/66 kHz).

All package types provide the following transparent features: Soft-start,132kHzswitching frequency (automatically reduced at light load), frequency jittering for lower EMI, wider DMAX 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.
