The ADP2114 evaluation (demo) board is a complete, dual, step-down, dc-to-dc converter design based on the ADP2114, a configurable, dual 2 A/single 4 A, synchronous step-down, dc-to-dc regulator.
The ADP2114 is a versatile step-down switching regulator that satisfies a wide range of user point-of-load requirements. The two PWM channels are 180° phase shifted and provide ±1.5% accurate regulated output voltages. For more details, see the ADP2114 data sheet.
The ADP2114 evaluation board comes in two versions: the ADP2114-EVALZ with 3.3 V at 2 A and 1.8 V at 2 A outputs, switching frequency set to 600 kHz, and pulse skip enabled, and the ADP2114-2PH-EVALZ with interleaved 1.2 V at 4 A single output, switching frequency set to 1.2 MHz, and forced PWM mode. If needed, the ADP2114 evaluation board output voltages and configuration can be modified by changing the values of the appropriate passive components and changing the links. The ambient temperature operation range is from −40°C to +85°C.
