The ADP2323 evaluation board is a complete, dual, 3 A step-down regulator solution that allows users to evaluate the performance of the ADP2323 with a near ideal printed circuit board (PCB) layout.

The two pulse-width modulation (PWM) channels can be configured to deliver dual, 3 A outputs or a parallel-to-single, 6 A output. The switching frequency can be programmed between 250 kHz and 1.2 MHz, or it can be synchronized to an external clock with a programmed 60°, 90°, or 120° phase shift, which provides the possibility for a stackable multiphase power solution.

The outputs of the ADP2323 evaluation board are preset to 1.2 V and 3.3 V for Channel 1 and Channel 2, respectively. With the PWM mode selected, the switching frequency is set to 500 kHz. Different output voltage settings and configurations can be achieved by changing appropriate passive components or jumper settings. The ambient temperature operating range is −40°C to +85°C.
