Description
Austin Lynx™ power modules are non-isolated dc-dc converters that can deliver 10 A of output current with full
load efficiency of 95% at 3.3 V output. These open frame modules in SIP package enable designers to develop
cost-and space efficient solutions. Standard features include remote ON/OFF, output voltage adjustment, over-
current and overtemperature protection.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute maximum stress ratings only. Functional operation of the device is not implied at these or any other conditions
in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect device reliability.

Fusing Considerations
CAUTION: This power module is not internally fused. An input line fuse must always be used.
To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and
system protection, always use an input line fuse. The safety agencies require a time-delay fuse with a maximum
rating of 20A.

Solder Ball and Cleanliness Requirements
This open frame (no case or potting) module will meet the solder ball requirements per J-STD-001B. These require-
ments state that solder balls must neither be loose nor violate the power module minimum electrical spacing. The
cleanliness designator of the open frame module is C00 (per J specification).
Feature Specifications
Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature
conditions. See Feature Descriptions and Design Considerations sections for further information.
