GENERAL DESCRIPTION:
The uPOL module is non-isolated dc-dc
converter that can deliver up to 3A of output
current. The PWM switching regulator, high
frequency power inductor are integrated in one
hybrid package. It only needs input/output
capacitors and one voltage dividing resistor to
perform properly.
The module has automatic operation with PWM
mode and power saving mode according to
loading, through constant on-time control, the
module offers a simpler control loop and faster
transient response. Other features include
remote enable function, internal soft-start,
non-latching over current protection, power
good, input under voltage locked-out capability.
The low profile and compact size package
(3.0mm × 2.8mm x 1.5mm) is suitable for
automated assembly by standard surface mount
equipment. The uPOL module is Pb-free and
RoHS compliance.
