DESIGN IDEASвЂ‰L High Voltage Step-Down Controller
Delivers High Power with Minimum
Number of Components
by Stephanie Dai and Theo Phillips Introduction
The LTC3824 is a non-synchronous
buck controller that accepts inputs
from 4V to 60V and is robust in the
presence of large input transient
voltages (FigureВ 1). It draws just
40ВµA of quiescent current in Burst
Mode operation, prolonging run time
in battery-powered applications. To
handle the wide range of temperatures
found in automotive and industrial
applications, the LTC3824 comes in
a thermally enhanced 10-pin MSE
package. 12V/2A from a
Wide Input Voltage Range A typical LTC3824 application (FigureВ 2) can deliver up to 2A of
continuous load current, and provides
up to 90% efficiency at 1A (FigureВ 3).
Sturdy 2A, 8V gate drivers accommodate industrial high voltage P-channel
MOSFETs. By using a P-FET as a main
switch, the controller is able to operate …
