Description
- DC2527A-B, Demonstration Circuit features the LTM4646EY, a dual 10A or single 20A high efficiency, switch mode step-down power regulator. The input voltage range is from 4.5V to 20V. With CPWR bias, input voltage can be as low as 2.375V. The output voltage range is 0.6V to 5.5V. De-rating is necessary for certain VIN, VOUT, frequency and thermal conditions. The DC2527A-B offers the TRACK/SS pin allowing the user to program output tracking or soft-start period. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the MODE_PLLIN jumper can select discontinuous conduction mode. The MODE_PLLIN pin also allows the LTM4646 to synchronize to an external clock signal (between 300kHz and 1.3MHz). The DC2527A-B has the option of choosing both internal and external compensation circuit for LTM4646
