EVALUATION BOARD DESCRIPTION
The ADP1864 evaluation board is designed to be used with the
ADP1864 Buck Design Software. The evaluation board is con-
figured 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 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.
For more details, see the ADP1864 data sheet.
