REF_ICC80QSG_84W2_BPA
Overview
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.
Summary of Features
- 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
Benefits
- 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
Potential Applications
- Battery chargers
- Light electric vehicles such as e-bikes
