GENERAL DESCRIPTION
The ADP2102 evaluation board is a complete step-down, dc-to-dc
converter solution using the
converter solution using the
step-down, dc-to-dc
converter. It provides a ±1% accurate (±2% over all conditions)
regulated output voltage with load currents up to 600 mA. It
comes in two versions: fixed output with output voltages ranging
from 0.8 V to 1.875 V and adjustable output with output voltages
regulated output voltage with load currents up to 600 mA. It
comes in two versions: fixed output with output voltages ranging
from 0.8 V to 1.875 V and adjustable output with output voltages
ranging from 0.8 V to 3.3 V. Refer to the Ordering Guide for
details on the available models.
details on the available models.
The ADP2102 is a synchronous, step-down, dc-to-dc converter,
which uses a constant on-time, valley current mode control
scheme to regulate the output voltage. At medium-to-heavy
load currents, the ADP2102 operates in continuous conduction
mode (CCM) for high efficiency and smoothly transitions to
a power-save mode (PSM) at light loads to conserve power.

The power switch and synchronous rectifier are integrated for
minimal external part count and high efficiency. The ADP2102
is optimized for operation with small ceramic inductors and
tiny ceramic capacitors to deliver the maximum output power
per square inch of the PCB board area.
