Overview

The NCP1360 offers a new solution targeting output power levels from a few watts up to 20 W in a universal-mains flyback application.Thanks to a novel method this new controller saves the secondary feedback circuitry (opto-coupler and TL431 reference) while achieving excellent line and load regulation.The NCP1360 operates in valley lockout quasi-resonant peak current mode control mode at high load to provide high efficiency. When the power on the secondary side starts to diminish, the controller automatically adjusts the duty-cycle then at lower load the controller enters in pulse frequency modulation at fixed peak current with a valley switching detection. This technique allows keeping the output regulation with tiny dummy load. Valley lockout at the first 4 valleys prevent valley jumping operation and then a valley switching at lower load provides high efficiency.

  • No frequency clamp, 80 or 110 kHz Maximum Switching Frequency
  • Quasi-Resonant with Valley Switching Operation
  • Fixed Peak Current & Deep frequency foldback @ light load operation
  • Cycle by Cycle peak current limit
  • Wide Operation VCC range (up to 28 V)
  • Internal Temperature Shutdown
  • CS & Vs/ZCD pin Short and Open Protection
  • Constant Current Primary-side feedback eliminates secondary controller
  • ±10% Current Regulation
  • Build-in soft-sart
  • Clamped Gate-drive Output for Mosfet
  • Less than 30 mW No-Load Performance

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
