Texas Instruments LM63615 | Demoboard PMP22063

Description

This reference design provides the system rails for automotive HUD, center information display, cluster display, or other automotive displays. A 3.3V bus is generated by an off-battery buck converter. A boost converter provides 3.3V to 5V conversion and a buck provides 1.8V from the 3.3V 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 limits
• All switching converters operating above 2 MHz to avoid AM band
• High light-load efficiency to reduce standby current consumption
• Less than 25°C temperature rise under full load current conditions for all switching converters
• Stable converter operation with over 45° phase margin and over 10-dB gain margin

Typical applications

• Entry level instrument cluster / Head-up display / Hybrid instrument cluster / Motorcycle instrument cluster / Reconfigurable instrument cluster
• Automotive auxiliary display / Automotive center information display / Automotive cluster display / Commercial vehicle instrument cluster
