EUP3466
CC/CV Mode Step-Down Converter
DESCRIPTION
The EUP3466 is a step-down converter capable of
driving 3A continuous load with excellent line and
load regulation. The EUP3466 operates in either CC
(Constant Current) mode or CV (Constant Voltage)
mode with an input voltage range from 8V to 36V. The
EUP3466 provides programmable cable compensation
by adjusting external resistor divider. The EUP3466
stops switching when the output reaches over voltage
threshold which is programmed by external resistor
divider.
Fault protection includes secondary cycle-by-cycle
current limit, short circuit protection and thermal
shutdown. In shutdown mode the regulator draws 3µA
of supply current. Internal soft-start minimizes the
inrush supply current and the output overshoot at initial
startup.
The EUP3466 is available in SOP-8 package.
