Beschreibung

This reference design is an EMI-optimized design for automotive USB Type-A charger with single 12-W output. The TPS25846-Q1 is used as DC-DC regulator and port controller. The switching frequency is 400kHz. The front-end filter is designed and PCB layout is optimized to pass stringent CISPR 25 Class 5 Conducted Electromagnetic Interference (EMI) standards. This reference design has already been tested to CISPR 25 Class 5 conducted EMI standards, which accelerates design time.

Eigenschaften

  • Pass stringent CISPR 25 Class 5 Conducted Electromagnetic Interference (EMI) standards
  • 95.2% peak efficiency
  • Cross regulation within ±1% of 5V rail
  • 400k-Hz switching frequency for small PCB dimension

Typische Anwendungen

  • Automotive USB charge
