综述

84 W AC-DC reference design for e-bike battery charger

The REF_ICC80QSG_BPA2_84W is an 84 W flyback-based reference design tailor-made for battery chargers for e-bikes.  It is based on the quasi-resonant flyback controller ICC80QSG and the renowned 700 V CoolMOS™ P7 technology in the small footprint and wave solderable SOT-223 package. 

特征描述

  • Secondary-side regulation with adjustable CC output set-point from 0.2 A to 2 A
  • Supports wide output load range from 6 V to 42 V
  • Full-power efficiency more than 91 percent at 230 VRMS_AC input
  • Four-point average efficiency more than 91 percent at 42 V output load 
  • System standby power less than 200 mW at 230 VRMS_AC input

优势

  • High efficiency and low EMI with quasi-resonant (QR) valley switching
  • Cost-effective flyback MOSFET with high performance, using CoolMOS™ P7 in SOT-223 package
  • Configurable hysteresis of brown-in and brown-out
  • Adaptive brown-out level triggering based on bus voltage ripple, to better protect primary components from overheating and saturation with higher brown-out level at higher power transfer
  • Comprehensive set of protections: internal overtemperature protection (OTP), output overvoltage protection (OVP), VCC OVP, overcurrent protection (OCP), brown-in and brown-out protection, input OVP and open-loop protection
