EUP3270WIR1 降压芯片4A同步整流降压转换器

DESCRIPTION
The EUP3270 is a synchronous step-down converter
capable of driving 4A continuous load with excellent
line and load regulation. The EUP3270 operates in
either CC (Constant Current) mode or CV (Constant
Voltage) mode with an input voltage range from 4.5V
to 30V. The EUP3270 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 EUP3270 is available in SOP-8 (EP) package.
