Description
The 20A Analog Micro DLynxTM power modules are non-isolated dc-dc converters that can deliver up to 20A of
output current. These modules operate over a wide range of input voltage (VIN = 3Vdc-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 Tunable LoopTM
feature 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.
