Automotive cluster and display power reference design with warm/cold-crank capability
Description
This reference design provides the system rails for automotive HUD: center information display: cluster display: or other automotive displays. A 3.3-V bus is generated by an off-battery buck converter. A boost converter provides 3.3-V to 5-V conversion and a buck provides 1.8 V from the 3.3-V rail. Display panel: CAN bus: microcontroller (MCU): FPD-Link: touch controller and switch packs are all examples of what can be driven by the power rails in this design. EMI filtering and reverse battery protection are included.
Features
- Hardware tested automotive infotainment display unit power tree passing CISPR 25 conducted EMI limitsAll switching converters operating above 2 MHz to avoid AM bandHigh light-load efficiency to reduce standby current consumptionLess than 25 °C temperature rise under full load current conditions for all switching convertersStable converter operation with over 45 ° phase margin and over 10-dB gain margin
