CSD16325Q5 – TEXAS INSTRUMENTS

The CSD16325Q5 is a 30V, 20A synchronous buck converter MOSFET from Texas Instruments, packaged in a space-saving, thermally efficient PQFN-20 (5x6mm) package. Its key feature is its extremely low R_DS(on) of typically 2.5mΩ, contributing to high efficiency even at high currents. This is achieved through its advanced trench-FET technology. The device boasts a robust gate charge (Q_g) of approximately 16nC, enabling fast switching speeds suitable for applications demanding high switching frequencies. Typical V_GS operating range is -4V to +8V, allowing for flexible gate drive design._x000D_

This MOSFET is ideal for applications requiring high power density and efficiency in a compact footprint, such as portable power supplies, battery chargers, and DC-DC converters in automotive and industrial settings. Its low R_DS(on) minimizes conduction losses, while its fast switching speed reduces switching losses, resulting in overall improved efficiency and reduced heat dissipation. The PQFN package facilitates efficient heat transfer to the PCB, further enhancing thermal performance. Designers should note the need for appropriate gate drive circuitry to fully leverage its switching speed capabilities and ensure reliable operation within the specified voltage range. The CSD16325Q5’s low R_DS(on) and compact size make it a strong contender where size and efficiency are paramount.
