Automotive buck-boost controller reduces size of vehicle USB PD

Maxim Integrated claims that its MAX25430 automotive buck-boost controller enables automotive USB Power Delivery (USB PD) ports at a size which is up to 40 per cent less than competing alternatives. It also eliminates microcontrollers, metal enclosures and heat sinks to reduce cost by up to 25 per cent, compared with the same alternatives.

Maxim says that the MAX25430 100W USB PD buck-boost controller and protector presents designers of automotive chargers with the industry’s smallest and lowest-cost solution for automotive multimedia hubs, including rear-seat entertainment modules and head-units in passenger vehicle cabins.

The MAX25430 integrates a USB Type C Port Controller (TCPC) power regulator, Vconn cable power supply, buck-boost and protection to eliminate heat sink requirements and metal box enclosures.

The MAX25430 runs 20 degrees C cooler at full power compared to competitive automotive USB PD products, Maxim reports. It needs a single microcontroller regardless of the number of ports, and competitors’ devices require additional microcontrollers per port.

Maxim Integrated also offers the MAX25410 automotive USB PD port protector and the MAX25431 automotive 40V H-bridge buck-boost controller for an array of USB charger design needs.

Richard Robinson, automotive director at Strategy Analytics, commented that the market will increase nearly 10x between 2020 (5.7 million units) and 2027 (50 million units), where USB PDs will be used for in-cabin requirement for higher power and faster data transfer on consumer devices.

Maxim Integrated develops analogue and mixed-signal products and technologies to make systems smaller and smarter, with enhanced security and increased energy efficiency.
