Description

This synchronous buck converter was designed for a high-current automotive Engine Control Unit (ECU). This design combines the TPS59632-Q1, 24-V, 3-phase step-down driverless controller and state-of-the-art automotive DrMOS. The compact size and high efficiency make the design an excellent choice for low-voltage, high-current rails in automotive applications.
