Demonstration circuit 1934A is a 40V, 3.5A step-down μModule® regulator featuring the LTM8053. The demo board is designed for 5V output from a 5.6V to 40V input. The wide input range allows a variety of input sources, such as automotive batteries and industrial supplies. The user adjustable features of the LTM8053 such as output voltage, switching frequency, soft-start, and power good can be changed on DC1934A simply by modifying the appropriate resistors and/or capacitors. Two or more LTM8053s can be paralleled to share load current equally.
