The ADP2165/ADP2166ACPZ-1.0-R7 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/ADP2166ACPZ-1.0-R7 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/ADP2166ACPZ-1.0-R7 are designed to be extremely flexiblewith the addition of a minimal amount of external componentsto program soft start and control loop compensation.
he ADP2165/ADP2166ACPZ-1.0-R7 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/ADP2166ACPZ-1.0-R7 operate over the −40°C to +125°Cjunction temperature range and are available in a 24-leadLFCSP package.
