ACE4940M Datasheet, PDF (1/7 Pages) ACE Technology Co., LTD. – Dual N-Channel 40-V MOSFET

ACE4940M
Dual N-Channel 40-V MOSFET
Description
The ACE4940M uses advanced trench technology to provide excellent R_DS(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
