The DC1379B demonstration board is a step down DC to DC switching regulator featuring LTM8025EV μModule regulator. The LTM8025 is a 36VIN, 3A step down μModule converter. Included in the IC package are the switching controller, power switches, inductor and all support components. The demonstration board is designed to deliver a 3.3V output from a 5.5V to 36V input. The modes of operation (Burst mode operation or synchronization) are jumper selectable. Burst mode operation improves efficiency at light loads. The LTM8025EV can be synchronized over a 250KHz to 2MHz range. The current mode control scheme creates fast transient response and good loop stability. The RUN/SS pin can be used to set the part in micropower shutdown mode reducing the supply current to less than 1μA. The RUN/SS pin can also be used to program soft start. In this mode, the RUN/SS pin is driven through an external RC filter to create a voltage ramp on this pin reducing the input current surge during start up.
