Adjustable frequency: 250 kHz to 1.4 MHz  
Synchronizes to external clock: 250 kHz to 1.4 MHz  
Selectable synchronize phase shift: in phase or out of phase  
External compensation  
Figure 1.  
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.  
Programmable soft start  
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 adjustable options 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.  
Startup into a precharged output  
Voltage tracking input  
Power-good output and precision enable input  
Accurate current limit  
Available in 24-lead, 4 mm × 4 mm LFCSP package  
Supported by ADIsimPower™ design tool  
APPLICATIONS  
The ADP2165/ADP2166 operate over the −40°C to +125°C  
junction temperature range and are available in a 24-lead

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
