Product Details

Demonstration circuit DC3016A is a buck-boost power supply featuring the LTM4693, ultrathin, highly efficient, 2A buck-boost μModule^® regulator. The LTM4693 regulates an output voltage above, below, or equal to the input voltage. This demonstration circuit is designed to have an input voltage from 2.6V to 5.5V with selectable 1.8V, 2.5V, 3.3V, and 5V output voltage up to 2A load. Derating may be necessary for specific V_IN, V_OUT, and thermal conditions.

This demo board includes a mode selector that allows the converter to run in CCM or Burst Mode^® operation. Synchronization to an external clock is also possible. The switching frequency can be adjusted from 1MHz to 4MHz by a resistor. And the soft-start period is programmable by an external capacitor. The LTM4693 data sheet gives a complete description of these functions, operation, and application information. The data sheet must be read in conjunction with this quick start guide for demo circuit 3016A.
