Information

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).

Key Features

  • 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
  • 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
