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
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 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.
