ACE4940M

Dual N-Channel 40-V MOSFET

VER 1.2

1

Description

The ACE4940M uses advanced trench technology to provide excellent RDS(ON) and low gate charge. This

device is suitable for use as a load switch or in PWM applications. The source leads are separated to

allow a Kelvin connection to the source, which may be used to bypass the source inductance.

Features

• Low r

DS(on) trench technology

• Low thermal impedance

• Fast switching speed

Applications

• White LED boost converters

• Automotive Systems

• Industrial DC/DC Conversion Circuits
