PD-93839A IRLR8503 IRLR8503 • N-Channel Application-Specific MOSFET HEXFET® MOSFET for DC-DC Converters • Ideal for CPU Core DC-DC Converters • Low Conduction Losses D • Minimizes Parallel MOSFETs for high current applications Description This new device employs advanced HEXFET Power G 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 S D-Pak generation of microprocessors. The IRLR8503 has been optimized and is 100% tested for all parameters that are critical in synchronous buck DEVICE RATINGS (MAX. Values) converters including RDS(on), gate charge and Cdv/dt- induced turn-on immunity. The IRLR8503 offers an IRLR8503 extremely low combination of Qsw & RDS(on)
