LTM8052 DC to DC Converter and Switching Regulator Chip 2.375VDC to 2.625VDC Output Demonstration Circuit

The demonstration board features LTM8052EV device. The LTM8052EV is a 36VIN, 5A two quadrant constant voltage constant current CVCC step down µModule regulator. Included in the IC package are the switching controller, power switches, inductor and support components. The demo circuit is designed for a 2.5V output from an input voltage range of 6V to 36V. The output can source 5A or sink 5A. The circuit can be operated in either constant voltage mode or constant current mode. When the output sinks current, the circuit maintains its output voltage regulation by power conversion, not power dissipation. This means that the energy provided to LTM8052 is in turn delivered to its input power bus There must be something on the input power bus to accept or use the energy.
