Per the company, the MAX25430 decreased design size up to 40 percent and eliminates microcontrollers, metal enclosures, and heat sinks for 25 percent lower cost than competitive solutions.

According to Maxim Integrated, designers of automotive chargers, the company now has the industry’s smallest and lowest-cost solution with the MAX25430 100W USB Power Delivery (PD) buck-boost controller and protector. Per the company, the MAX25430 can reduce design size up to 40 percent compared to competitive solutions and offer the industry’s lowest cost for increasing the number of USB PD ports in vehicles.

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. According to the company bill-of-materials (BOM) costs are also reduced by 25 percent compared to competitive solutions. The MAX25430 runs 20-degrees (Celsius) at full power. Also, it needs only one microcontroller (MCU) regardless of the number of ports.

Maxim Integrated also offers the MAX25410 automotive USB PD port protector and the MAX25431 automotive 40V H-bridge buck-boost controller.
