Demonstration circuit 2327A is a step-down DC/DC converter with 28V to 58V input voltage, 24V output voltage and max 4A output featuring the LTM4653Y. The LTM®4653 is an ultralow noise, 58V, 4A step-down DC/DC μModule regulator. It is designed to meet the radiated emissions requirement of EN55022B. A switching frequency range of 250kHz to 3MHz is supported and the module can synchronize to an external clock. The LTM4653 data sheet must be read in conjunction with this demo manual prior to working on or modifying demo circuit DC2327A.
