Infineon Technologies ICC80QSG | Demoboard REF_ICC80QSG_84W1_BPA

Beschreibung

The REF_ICC80QSG_84W1_BPA is a flyback-based reference design, scalable from 65 W to >100 W and aimed for 12 V/18 V Li-Ion battery packs. 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. The controller burst mode enables low standby <200 mW. The reference board includes a secondary-side auxiliary supply for battery switch and supply of a MCU. Measured efficiency is >90 percent at 230 VAC input voltage, providing excellent performance versus BOM cost ratio for chargers for consumer appliances.

Eigenschaften

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

Typische Anwendungen

• PC, TV, Audio amplifier applications up to 130 W
• Battery charging up to 130 W, Power tools, E-bikes
