Efficient, low-heat, CISPR 25 class 5-compliant power reference design for infotainment display

Details

TopologieAbwärtswandler
Eingangsspannung8-18 V
Schaltfrequenz250-2200 kHz
Ausgang 15 V / 1.5 A
IC-RevisionE1

Beschreibung

This reference design is focused on the power tree for an automotive infotainment display unit covering various power supply rails including two off-battery converters providing 5.0-V and 3.3-V, and intermediary system rails of 1.8-V and 1.1-V. The test results demonstrate high efficiency, low heat dissipation and CISPR 25 class 5-conducted emissions compliance.

Eigenschaften

  • Hardware tested automotive infotainment display unit power tree passing CISPR 25 class 5-conducted EMI limits
  • All switching converters operating above 2-MHz to avoid AM band
  • High light load efficiency to reduce standby current consumption
  • Less than 30oC temperature rise under full load current conditions for all switching converters
  • Stable converter operation with over 65o phase margin and over 20-dB gain margin

Typische Anwendungen

  • Automotive infotainment: telematics control unit / Automotive body: gateway / Automotive ADAS: mirror replacement/CMS
