This new device employs advanced HEXFET Power 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 RDS(on), gate charge and Cdv/dtinduced turn-on immunity. The IRLR8503 offers an extremely low combination of Qsw & RDS(on) for reduced losses in control FET applications.
The package is designed for vapor phase, infra-red, convection, or wave soldering techniques. Power dissipation of greater than 2W is possible in a typical PCB mount application.
