... MOSFET technology to achieve very low on-resistance. The reduced conduction losses makes it ideal for high efficiency DC-DC converters that power the latest generation of microprocessors. The IRLR8503 has been optimized and is 100% tested for all parameters that are critical in synchronous buck converters including R , gate charge and Cdv/dt- DS(on) induced turn-on immunity ...

... Power MOSFET Optimization for DC-DC Converters While the IRLR8103V and IRLR8503 can and are be- ing used in a variety of applications, they were designed and optimized for low voltage DC-DC conversion in a synchronous buck converter topology, specifically, mi- croprocessor power applications. The IRLR8503 (Fig- ...
