REFICC80QSG84W2BPATOBO1

REFICC80QSG84W2BPATOBO1 is a 84W flyback-based reference design tailor-made for battery chargers for e-bikes. This evaluation board is based on the quasi-resonant flyback controller ICC80QSG and the renowned 700V CoolMOS™ P7 technology in the small footprint and wave solderable SOT-223 package. 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. The comprehensive set of protections are 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 are battery chargers, light electric vehicles such as e-bikes.
