DC2251A

DC2251A demonstration circuit is a 40V, 3.5A peak, 2.5A continuous step-down μModule® regulator featuring the LTM®8065. The demo board is designed for 5V output from a 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 LTM8065 such as output voltage, switching frequency, soft-start and power good can be changed on DC2251A simply by modifying the appropriate resistors and/or capacitors. The LTM8065 can be programmed to different operation modes. The SYNC pin on the demo board is grounded (JP1 at BURST position) by default for low ripple Burst Mode® operation. Pulse-skipping mode, spread spectrum mode or synchronization mode can be selected respectively by moving JP1 shunt to SYNC position and adding different signals to SYNC terminal.
