Description
The 7A Analog PicoDLynxII
TM
power modules are non-isolated dc-dc converters that can deliver up to 7A of output current. These
modules operate over a wide range of input voltage (V
IN
= 4.5Vdc-14.4Vdc) and provide a precisely regulated output voltage from
0.6Vdc to 5.5Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over current
and over temperature protection. The module also includes the Tunable Loop
TM
feature that allows the user to optimize the
dynamic response of the converter to match the load with reduced amount of output capacitance leading to savings on cost and
PWB area.

Absolute Maximum Ratings
Data Sheet
7A Analog PicoDLynxII

: Non-Isolated DC-DC Power Modules
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute 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 the device reliability.
