1 Specifications of the Board

The LM2742 Evaluation board has been designed for a wide variety of components in order to show the flexibility of the LM2742 IC. The example design steps input voltages from 2.0 V to 13.2 V, down to 1.2 V, at 4 A, with a switching frequency of 500 kHz. This design can be modified by following the Design Considerations section of the LM2742 N-Channel FET Synchronous Buck Regulator Controller for Low Output Voltagesd ata sheet. The board is four layers, consisting of signal/power traces on top and bottom, one internal ground plane, and an internal split power plane. All planes are 1-oz. copper, and the board is 62-mil FR4 laminate.
