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

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 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.  
The ADP2165/ADP2166 operate over  
the -40 to +125 junction temperature range and  
are available in a 24-lead LFCSP_WQ package.
