GENERAL DESCRIPTION:
The uPOL module is non-isolated DC-DC
converters that can deliver up to 1A of output
current. The PWM switching regulator, high
frequency power inductor are integrated in one
hybrid package. It only needs some passive
component to use this uPOL module easily.
The module has automatic operation with PWM
mode and power saving mode according to
loading. Other features include remote enable
function, internal soft-start, non-latching over
current protection.
The low profile and compact size package
(3.5mm × 3.5mm x 1.7mm) is suitable for
automated assembly by standard surface mount
equipment. The uPOL module is Pb-free and
RoHS compliant.
The wide input voltage range offers high
tolerance to the extreme automotive working
conditions (e.g. cold-crank, load-dump).
