Part Number: top246yn

Description

The top246yn is a  high voltage power MOSFET, PWM control, and other control circuitry is implemented on a single CMOS chip, like TOPSwitch. Many new features have been included to help lower system costs and enhance design flexibility, energy efficiency, and overall performance. The TOPSwitch standard DRAIN, SOURCE, and CONTROL terminals are enhanced by either 1 or 3 extra pins. One of these extra pins enables the following: line sensing (OV/UV, line feed-forward/DC current limit, remote ON/OFF, synchronization to an external lower frequency, and frequency selection (132 kHz/66 kHz). Every type of package offers the following transparent features: soft-start, 132 kHz switching frequency (automatically reduced at light load), frequency jittering for lower EMI, wider dynamic thermal shutdown, and bigger creepage. Furthermore, the current limit, frequency, and PWM gain settings all have more stringent temperature and absolute tolerance limits to simplify design and improve system cost.

Features

  • Has features that remove or minimize the cost of external components
  • Sophisticated software to prevent stress and undershoot
  • Externally programmable current limit with precise current measurement
  • A larger duty cycle and smaller input capacitor for higher power
  • On Y/R/F packages, isolate current limit and line sense pins
  • Unexpected shutoffs are prevented by line under-voltage (UV) detection.
  • OV shutdown extends surge tolerance.
  • +2.5%). -> increased feed-forward with a duty cycle of +2.5% (DC+2.5%).
  • Noise reduction by frequency jittering
  • Zero load regulation without dummy loading
  • 132 kHz frequency lowers the size of the transformer and power supply
  • The video application’s Y/R/F package half-frequency option
  • Thermal shutdown for automated fault recovery with hysteresis
  • PC board heat stays away with large thermal hysteresis.
  • EcoSmart – an energy-efficient brand.
  • Very low power usage when in off mode
  • Reduction in frequency for improved standby efficiency with loading
  • can be turned on or off by LAN or input port

 

Application

The top246yn has various industrial applications such as inverters and power conversion circuits in a wide range of applications, including motor drivers, plasma display panels, uninterruptible power supply (UPS) systems, IH cookers, plasma display panels (PDPs), strobe flashes, and other similar devices.:
