GENERAL DESCRIPTION:
The uPOL module is non-isolated dc-dc
converter that can deliver up to 1000mA 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
(3.5mm × 3.5mm x 1.7mm) is suitable for
automated assembly by standard surface mount
equipment. The uPOL module is Pb-free and
RoHS compliance.

Description
Leave SS pin floating for default 1ms soft-start time. For longer than 1ms
soft-start time, connect a capacitor from SS to GND.
Tss(ms)=Css(nF)*0.6V/4uA
Feedback input. Connect an external resistor divider from the output to
GND to set the output voltage.
Power Good indicator. The pin output is an open drain that can connect to
VIN by resistor.
Power output pin. Connect to output for the load.
Power ground pin for signal, input, and output return path. This pin
needs to be connected to one or more ground plane directly.
No connection
On/Off control pin for module.
EN = LOW, the module is off.
EN = HIGH, the module is on.
Do not float.
Power input pin. It needs to be connected to input rail.
