Texas Instruments TPS28225 8-Pin High Frequency 4-Amp Sink Synchronous MOSFET Driver TPS28225DG4

The TPS28225 is an 8-pin high-frequency synchronous MOSFET driver designed to drive two N-channel MOSFETs with a maximum sink current of 4A. It features adaptive dead-time control with a propagation delay of 14ns and rise/fall times of 10ns, enabling high-frequency operation suitable for switching frequencies up to 2MHz. The driver operates with a wide gate drive voltage range of 4.5V to 8.8V, achieving optimal efficiency at 7V to 8V, and supports input PWM signals from 2.0V to 13.2V. This device is capable of driving MOSFETs with currents of 40A or more per phase, making it suitable for high-current applications such as multi-phase DC-to-DC converters, desktop and server voltage regulators, and synchronous rectification in isolated power supplies. It includes features such as thermal shutdown, undervoltage lockout (UVLO) protection, and an internal bootstrap diode, which enhances its reliability and performance in demanding environments. The TPS28225 is available in both SOIC-8 and thermally enhanced VSON-8 packages, providing flexibility for various design requirements.
