Product Details

Product Details

Demonstration circuit 2372A is a 5.5V input, 12V output at 400mA DC/DC power supply featuring the LTC3121. The IC includes internal high and low side 1.5A switches and features selectable PWM or Burst Mode^® operation for high efficiency at low output current. The board operates from an input voltage as low as 1.8V and continues to operate down to 500mV once started. The output is fixed at 12V although other voltages between 2.2V and 15V can be selected by resistor changes.
