GENERAL DESCRIPTION
The ADP2165/ADP2166 are high efficiency, current mode
control, step-down dc-to-dc regulators with an integrated 19 mΩ
high-side FET and a 15 mΩ synchronous rectified FET. The
ADP2165/ADP2166 combine a small size, 4 mm × 4 mm LFCSP
package with an accurate current limit, resulting in a smaller
inductor size and a high power density, point of load solution.
Key features include precision enable, power-good monitor,
and output voltage tracking to facilitate robust sequencing.
The switching frequency can be programmed from 250 kHz
to 1.4 MHz, or it can be fixed at 620 kHz or 1.2 MHz. The
synchronization function allows the switching frequency to
synchronize to an external clock, minimizing the
electromagnetic interference (EMI) of the system.

The ADP2165/ADP2166 are designed to be extremely flexible
with the addition of a minimal amount of external components
to program soft start and control loop compensation.
The ADP2165/ADP2166 are supplied from an input voltage of
2.7 V to 5.5 V. Output voltage options include 3.3 V, 2.5 V, 1.8 V,
1.5 V, 1.2 V, or 1.0 V fixed outputs and adjustableoptions capable
of supporting an output voltage range from 0.6 V to 90% of the
input voltage. Protection features include undervoltage lockout
(UVLO), overvoltage protection (OVP), overcurrent protection
(OCP), and thermal shutdown (TSD) for robust performance.
The ADP2165/ADP2166 operate over the −40°C to +125°C
junction temperature range and are available in a 24-lead
LFCSP_WQ package.
