40% reduction in size by eliminating heat sink and metal case
A USB PD hub can be configured with a single MCU.


As the number of USB Power Delivery (PD) chargers built into vehicles increases, the functionality of in-vehicle multimedia hubs, including rear-seat entertainment modules and head units, is expanding. This, in turn, is placing increasing pressure on designers regarding size, cost, and power.

Maxim Integrated Korea announced on the 14th the availability of the MAX25430, a 100W USB PD buck-boost controller and protector. Automotive charger designers can now implement the industry's lowest-cost USB PD hub with the MAX25430, which is 40% smaller than competing solutions.

The MAX25430 integrates a USB-C port controller (TCPC) power regulator, VCONN cable power supply, buck-boost, and protection, while eliminating the heatsink and metal case to reduce size by up to 40% compared to competing multi-ICs. It also reduces cost by 25% by enabling implementation with a single MCU, regardless of the number of ports. With a 20 degree lower heat dissipation temperature at maximum output, it delivers robust performance even in harsh environments.

Maxim also offers the MAX25410 automotive USB PD port protector and the MAX25431 automotive 40V H-bridge buck-boost controller to meet the diverse needs of USB charger designs and support complete solutions.
