The ADP2165/ADP2166 are high efficiency, current modecontrol, step-down dc-to-dc regulators with an integrated 19 mΩhigh-side FET and a 15 mΩ synchronous rectified FET. TheADP2165/ADP2166 combine a small size, 4 mm × 4 mm LFCSPpackage with an accurate current limit, resulting in a smallerinductor 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 kHzto 1.4 MHz, or it can be fixed at 620 kHz or 1.2 MHz. Thesynchronization function allows the switching frequency tosynchronize to an external clock, minimizing theelectromagnetic interference (EMI) of the system.The ADP2165/ADP2166 are designed to be extremely flexiblewith the addition of a minimal amount of external componentsto program soft start and control loop compensation.he ADP2165/ADP2166 are supplied from an input voltage of2.7 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 capableof supporting an output voltage range from 0.6 V to 90% of theinput 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°Cjunction temperature range and are available in a 24-leadLFCSP package.Applications Point of load regulation Communications and networking High end consumer Industrial, instrumentation, and healthcare
