The onsemi FDMF6705B, an XS™ DrMOS component, is a high-performance half-bridge driver designed for synchronous buck converters. This device integrates a driver and MOSFETs into a single 40-PQFN (6x6) package, facilitating compact and efficient power solutions. It supports a wide input voltage range of 3V to 24V with a supply voltage of 4.5V to 5.5V. Key features include a 38A output current capability per channel, bootstrap circuitry for high-side driving, and comprehensive fault protection including over-temperature, shoot-through, and UVLO. The FDMF6705B utilizes PWM interface for control and is suitable for inductive load types. Its robust design and surface mount configuration make it ideal for applications in computing, graphics cards, and high-density power systems. The component operates within an ambient temperature range of -40°C to 150°C (TJ).
