Description

The 20A Analog MicroDLynx

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 (V

= 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 module also includes the Tunable Loop

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.

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.

To initiate simultaneous shutdown of the modules, the SEQ pin voltage is lowered in a controlled manner. The output voltage of the modules tracks the voltages below their setpoint voltages on a one-to-one basis.

External capacitors are usually added to the output of the module for two reasons: to reduce output ripple and noise (see Figure 38) and to reduce output voltage deviations from the steady-state value in the presence of dynamic load current changes.
