DC1669A - LTM4627EV Demo Board | 20V, 15A Step-Down uModule Regulator

Demonstration circuit 1669A features the LTM®4627EV μModule® regulator, a high performance high efficiency step-down regulator. The LTM4627EV has an operating input voltage range of 4.5V to 20V and is able to provide an output current of up to 15A. The output voltage is programmable from 0.6V to 5V and can be remotely sensed with the internal optional differential remote sensing amplifi er. The LTM4627EV is a complete DC/DC point-of-load regulator in a thermally enhanced 15mm × 15mm ×4.32mm LGA package requiring only a  few input and output capacitors. This regulator is internally compensated and employs constant frequency current mode architecture, enabling a fast transient response and  stable control loop over a wide range of output capacitance. It supports frequency synchronization and Burst Mode® operation for increased light-load efficiency. Output voltage  tracking is also available through the TRACK/SS pin for supply rail sequencing.
