Beschreibung
LM5140 and LM5150 on the evaluation board.This reference design shows a complete power tree for automotive infotainment systems. The LM74700-Q1 provides reverse polarity protection to the system. The pre-booster with LM5150-Q1 provides a stable supply voltage of 10.5V during cranking for the dual-synchronous buck converter with LM5140-Q1, that provides an output voltage of 3.3V for a load current of 6.0A and an output voltage of 7.5V for a load current of 2.5A.
Eigenschaften
- Automotive power system reference design
- Supports input voltage down to 3.2V
- Reverse polarity protection
- Small form factor
Typische Anwendungen
- Rear Seat Entertainment / Reconfigurable Digital Cluster / Hybrid Cluster with Active Graphics Support
