EUP3268A
CC/CV Mode Synchronous
Step-Down Converter
DESCRIPTION
The EUP3268A is a synchronous step-down converter
capable of driving 4A continuous load with excellent
line and load regulation. The EUP3268A operates in
either CC (Constant Current) mode or CV (Constant
Voltage) mode with an input voltage range from 8V to
36V. The EUP3268A provides programmable cable
compensation by adjusting external resistor divider.
External shutdown function can be controlled by
pulling COMP pin to a level below 0.14V.
Fault protection includes secondary cycle-by-cycle
current limit, short circuit protection and thermal
shutdown. Internal soft-start minimizes the inrush
supply current and the output overshoot at initial
startup.
The EUP3268A is available in SOP-8 (EP) package.
