The CSD18563Q5A is a 60V, 100mΩ, 12A synchronous buck converter MOSFET from Texas Instruments, packaged in a compact, thermally efficient PQFN-20 (5x6mm) leadless package. This device features extremely low RDS(on), enabling high efficiency in power conversion applications, particularly where minimizing conduction losses is critical. Its internal body diode reduces switching losses compared to traditional MOSFETs. Typical operating voltage ranges from 4.5V to 60V, making it suitable for a wide array of input voltages._x000D_

The CSD18563Q5A boasts a fast switching speed, contributing to smaller output ripple and improved transient response. Its robust design incorporates features like avalanche ruggedness and short-circuit protection, enhancing reliability in demanding environments. Common applications include intermediate bus converters in high-power systems, point-of-load converters for FPGAs or ASICs, and battery-powered devices requiring high efficiency. The low thermal resistance of the PQFN package allows for operation at higher currents without requiring extensive heatsinking, simplifying board design and reducing overall system size. Designers should consider this part when high efficiency, compact size, and robust performance are paramount.
