GENERAL DESCRIPTION
The ADP2114 evaluation (demo) board is a complete, dual,
step-down, dc-to-dc converter design based on the
step-down, dc-to-dc converter design based on the
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.
