The FDMF5839 is a Smart Power Stage (SPS) module designed for high-current, high-frequency synchronous buck DC-DC applications. It features an ultra-compact 5 mm x 5 mm PQFN package and can handle a maximum current of 35 A. The module integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode, optimizing dynamic performance and minimizing system inductance. Key functionalities include a 3-state 5 V PWM input for compatibility with various PWM controllers, dynamic resistance mode for low-side drive, and an Auto DCM mode for improved light-load efficiency. The FDMF5839 also incorporates thermal warning and shutdown features to protect against over-temperature conditions. It is optimized for switching frequencies up to 1.5 MHz and has a low shutdown current of less than 3 ¬µA. The operating junction temperature range is from -40¬8C to +125¬8C, and it is automotive qualified to AEC-Q100. This product is suitable for applications such as notebook and tablet PCs, servers, high-performance gaming motherboards, and automotive systems.
