Analog Devices ADP1850 Handbook
The ADP1850 is a configurable dual‑output (or two‑phase single‑output) synchronous buck controller that operates from 2.75 V to 20 V inputs. It supports programmable switching frequencies from 200 kHz to 1.5 MHz and provides accurate current sharing between interleaved phases for high‑current applications.
Typical applications include point‑of‑load power supplies for telecom base stations, consumer electronics, industrial instrumentation, and medical equipment. The device integrates a boost diode, internal linear regulator, and multiple protection mechanisms such as over‑voltage, over‑current, undervoltage lock‑out, and thermal shutdown. Pin configurations, block diagrams, and layout guidelines are provided for designers.
