N- and P-Channel 30-V Power MOSFET
GENERAL DESCRIPTION
The LT4542 is the N- and P-Channel logic enhancement mode
power field effect transistors are produced using high cell density ,
DMOS trench technology. This high density process is especially
tailored to minimize on-state resistance. These devices are
particularly suited for low voltage application such as cellular phone
and notebook computer power management and other battery
powered circuits where high-side switching, and low in-line power
loss are needed in a very small outline surface mount package.
