LT3972 Step-Down Switching Regulator Demonstration Circuit 1458 User Guide
User guide for Demonstration Circuit 1458 featuring the LT3972, a 3.5A step-down switching regulator with an input range of 6.3V to 33V and 5V output.
Overview
Demonstration circuit 1458 is a monolithic step-down DC/DC switching regulator evaluation board featuring the LT3972EMSE. The board is configured for a 5V output at up to 3.5A from an input range of 6.3V to 33V, with transient protection up to 62V. It supports synchronization over a 250 kHz to 2 MHz range and features jumper-selectable Burst Mode operation for enhanced efficiency at light loads. The LT3972 utilizes current mode control for fast transient response and includes an integrated boost diode. Additionally, the RUN/SS pin provides micropower shutdown and programmable soft-start to reduce input current surges.
