REFICC80QSG84W1BPATOBO1

REF-ICC80QSG-84W1-BPA is a flyback-based reference design, scalable from 65W to <gt/>100W and aimed for 12V/18V Li-Ion battery packs. It 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. The controller burst mode enables low standby <lt/>200mW. The reference board includes a secondary-side auxiliary supply for battery switch and supply of a MCU. Measured efficiency is <gt/>90 percent at 230 VAC input voltage, providing excellent performance versus BOM cost ratio for chargers for consumer appliances.

• Secondary-side regulated (SSR) constant current (CC) output
• High efficiency and low EMI with quasi-resonant (QR) mode, switching in valley n (QRMn)
• Efficiency <gt/> 90%, at 230VAC input and full-load condition
• Low standby power with reduced gate driver voltage in burst mode
• Standby power <lt/>200mW, at 230VAC input and no-load condition
• Configurable hysteresis of brown-in and brown-out
• Adaptive brown-out level triggering based on o/p power protect primary components from overheating
• Internal OTP, OVP, VCC OVP, MOSFET OCP, brown-in and out protection, i/p OVP, open loop protection
