Description
The Micro TLynxTM series of power modules are non-isolated dc-dc converters that can deliver up to 12A of output current.
These modules operate over a wide range of input voltage (VIN = 2.4Vdc-5.5Vdc) and provide a precisely regulated output
voltage from 0.6Vdc to 3.63Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output
voltage, over current and overtemperature protection, and output voltage sequencing (APTH versions). A new feature, the
Tunable LoopTM, 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
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.

Test Configurations
Design Considerations
Input Filtering
CURRENT PROBE
The Micro TLynxTM module should be connected to a low acimpedance source. A highly inductive source can affect the
stability of the module. An input capacitance must be placed
directly adjacent to the input pin of the module, to minimize input
ripple voltage and ensure module stability.
