General Description
This N-Channel MOSFET has been designed specifically to
improve the overall efficiency of DC/DC converters using
either synchronous or conventional switching PWM
controllers. It has been optimized for low gate charge, low
rDS(on) and fast switching speed.

Notes:
1: Starting TJ = 25°C, L = 1mH, IAS = 7.5A, VDD = 30V, VGS = 10V.
2: RθJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of the
drain pins.
