CSD87350Q5D Description

Short technical summary and product information.

The CSD87350Q5D from Texas Instruments is a 30V, N-channel synchronous buck NexFET power block designed for high-current, high-efficiency, and high-frequency operation. It features a dual N-channel configuration in a half-bridge topology and is housed in a compact 8-LSON (5mm x 6mm) package. With a continuous drain current of 40A at 25°C and typical system efficiency of 90% at 25A, it delivers excellent performance for demanding power supply designs. The device supports a maximum operating frequency of 1.5 MHz and is optimized for 5V gate drive applications. Key electrical specifications include a maximum drain-source on-resistance of 5.9 mOhm at 20A and 8V, a maximum gate charge of 10.9 nC at 4.5V, and a maximum input capacitance of 1770 pF at 15V. The device operates over a junction temperature range of -55°C to 150°C and is rated for surface mount assembly. The lead-free terminal plating, RoHS compliance, and halogen-free construction make it suitable for environmentally conscious designs. Applications include synchronous buck converters, voltage regulator modules, and high-density power supplies.
