Product Details

This describes the design, operation, and test results of the ADP1877 13 A evaluation board. The input range for this evaluation board is 6 V to 14 V, and the two regulated output voltages are set to 1.8 V and 1.05V, each with a maximum load current of 13 A. A switching frequency (fSW) of 600 kHz achieves a good balance between efficiency and the sizes of the power components.
