Product Details

The blank ADP1864 evaluation board is designed to be used with the ADP1864 Buck Design Software. The evaluation board is configured to provide 3.3 V output at 3 A over an input voltage range of 9 V to 12 V. Through a versatile layout that accommodates several packages and a powerful companion design tool, the ADP1864 evaluation board can provide a wide variety of solutions, including up to a 5.0 V output at 10 A from a 12 V input. Kelvin connection terminals provide an accurate means for measuring the input and output voltages.

The blank evaluation board is designed to use the ADP1864 as an asynchronous, step-down dc-to-dc converter that uses a current mode pulse-width modulation control scheme. The ADP1864 drives a P-channel MOSFET that regulates an output voltage as low as 0.8 V with ±1.25% accuracy (up to 85°C), for up to 10 A load currents, from input voltages as high as 14 V. The ADP1864 provides system flexibility by allowing accurate setting of the current limit with an external resistor, while the output voltage is easily adjustable using two external resistors.
