IRLR8103
IRLR8103 is HEXFET Chipset for DC-DC Converters manufactured by International Rectifier.
Description
These new devices employ advanced HEXFET® power MOSFET technology to achieve an unprecedented balance of on-resistance and gate charge.The reduced conduction and switching losses make them ideal for high efficiency DC-DC converters that power the latest generation of microprocessors.
S D-Pak
Both the IRLR8103 and IRLR8503 have been optimized and are 100% tested for all parameters that are critical in synchronous buck converters including RDS(on), gate charge and Cdv/dt-induced turn-on immunity.The IRLR8103 offers particulary low RDS(on) and high Cdv/dt immunity for synchronous FET applications. The IRLR8503 offers an extremely low bination of Qsw & RDS(on) for reduced losses in control FET applications.
The package is designed for vapor phase, infrared, convection, or wave soldering techniques. Power dissipation of greater than 80W is possible in a typical PCB mount application.
