Description
The 3A Analog PicoDLynxTM power modules are non-isolated dc-dc converters that can deliver up to 3A of output current. These
modules operate over a wide range of input voltage (V
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 Tunable Loop
to match the load with reduced amount of output capacitance leading to savings on cost and PWB area.

Absolute Maximum Ratings
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.
