Infineon Technologies ICC80QSG | Demoboard REF_ICC80QSG_84W1_BPA
ICC80QSG 84 W AC-DC reference design #1 with IPN70R450P7S
Overview
| Topology | Flyback Converter |
| Input voltage | 176-264 V |
| Output 1 | 21 V / 4 A |
| IC revision | 1.0 |
Description
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.
Features
- 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
Typical applications
- PC, TV, Audio amplifier applications up to 130 W
- Battery charging up to 130 W, Power tools, E-bikes
