DESCRIPTION

LTM8052A

36V, 5A, 2-Quadrant CVCC

Step-Down µModule Regulator

Demonstration circuit 1939 is a 36V, 5A, 2-quadrant CVCC

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 LTM8052A is in turn delivered to its input power bus.

BOARD PHOTO

There must be something on the input power bus to ac-

cept or use the energy.

The LTM8052A data sheet gives a complete description of

the part, operation and application information. The data-

sheet must be read in conjunction with this demo manual

prior to working on or modifying demo circuit 1939.
