Introduction

AI Translation

DK8318 is a power factor correction IC operating in critical conduction mode (CRM) and discontinuous conduction mode (DCM). It operates in CRM under heavy load and seamlessly transitions to DCM as the load decreases. The IC integrates a 700V/101mΩ low on-resistance GaN power switch, with built-in functions including soft start, input undervoltage protection, input power compensation, over-temperature protection, output undervoltage/overvoltage protection, and overcurrent protection. DK8318 can be used in conjunction with downstream topology controllers such as flyback, AHB, and LLC to build efficient and reliable power supply solutions, with a recommended power range of up to 180W.

Features

AI Translation
  • Ultra-low standby power: 25mW at 115Vac input and 39mW at 230Vac input; meets CoC V5 Tier2 and DoE VI efficiency standards without disabling PFC.
  • Wide-range AC input voltage: 85~265Vac.
  • Supports both critical conduction mode (CRM) and discontinuous conduction mode (DCM) operation.
  • Supports valley switching technology.
  • Output voltage segmentation: 400Vdc when AC input voltage >170V; 264Vdc when AC input voltage <146V.
  • Demagnetization detection without auxiliary winding.
  • Input power compensation.
  • Integrated 700V/101mΩ GaN power switch.
  • Integrated protection features: VCC UVLO, output OCP, output UVP and OVP, OTP, bypass diode short-circuit protection, and current sense resistor open-circuit protection.
