Analog Devices ADP2165ACPZ-R7 and ADP2166 Step-Down DC-DC Regulators are 5A and 6A high efficiency, current mode control devices with an integrated 19m high-side FET and a 15m synchronous rectified FET. ADP2165ACPZ-R7 and ADP2166 combine a small size, 4mm�4mm LFCSP package with an accurate current limit, resulting in a smaller inductor size and a high power density, point of load solution. These devices feature power-good output, precision enable input, and voltage tracking input. The switching frequency can be programmed from 250kHz to 1.4MHz, or it can be fixed at 620kHz or 1.2MHz. The synchronization function allows the switching frequency to synchronize to an external clock, minimizing the electromagnetic interference (EMI) of the system. ADP2165ACPZ-R7 and 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.ADP2165-EVALZ is a full-featured evaluation board that provides an easy way to evaluate ADP2165.
