Maxim Integrated has announced the MAX25430, a 100W USB Power Delivery (PD) buck-boost controller and protector. The MAX25430 can reduce design size up to 40% compared to competitive solutions and offer the industry’s lowest cost for increasing the number of USB PD ports in vehicles, according to Maxim.
Automotive multimedia hubs, including rear-seat entertainment modules and head units, are all expanding in capability as more USB PD chargers are integrated into passenger vehicle cabins. However, there are size, cost and power constraints. The MAX25430 was designed to addresses all of these.
The MAX25430 integrates a USB Type C Port Controller (TCPC) power regulator, VCONN cable power supply, buck-boost and protection thereby eliminating heat-sink requirements and metal box enclosures to further slash design size by 40% compared to competitive multi-IC solutions. In addition, bill-of-materials (BOM) costs are also reduced by 25% compared to competitive solutions. The MAX25430 runs 20-degrees (Celsius) cooler at full power compared to competitive automotive USB PD solutions. It needs only one microcontroller (MCU) regardless of the number of ports, while competitors require additional MCUs per port.
For a complete solution, Maxim Integrated also offers the MAX25410 automotive USB PD port protector and the MAX25431 automotive 40V H-bridge buck-boost controller, meeting a wide array of USB charger design needs.
- Smallest Size: Integrates TCPC power regulator, VCONN power cable supply, buck-boost and protection to reduce solution size up to 40 percent
- Lowest Cost: Eliminates heat sinks, enclosure boxes and multiple MCUs to yield 25 percent cost savings
- Power Performance: Robust performance in harsh automotive environments while running 20 degrees cooler than the closest competitor
The MAX25430BATLG/V+T is available at Maxim Integrated’s website for $4.17 (1000-up, FOB USA); also available from authorized distributors. The MAX25430AEVKIT# evaluation kit is available for $299
