GENERAL DESCRIPTION
The
evaluation board is a complete 600 mA, step-down
regulator solution that tests the ADP2108, a high efficiency, low
quiescent current step-down, dc-to-dc converter available in
WLCSP and TSOT packages. The evaluation board is available
in standard voltage options. See the Ordering Guide for avail-
able models.

The ADP2108 uses a proprietary high speed, current mode,
constant frequency PWM control scheme for excellent stability
and transient response. To ensure the longest battery life in
portable applications, the ADP2108 features a power-saving,
pulse frequency modulation (PFM) mode that reduces the
switching frequency under light load conditions. The 3 MHz
switching frequency minimizes the size of external components.
Full details on the ADP2108 are provided in the ADP2108 data
sheet available from Analog Devices, Inc., which should be
consulted in conjunction with this data sheet.
