Analog Devices ADP1870/ADP1871 Datasheet
This document describes the ADP1870 and ADP1871 adjustable power‑management ICs. It includes functional block diagrams, pin‑out tables, and recommended operating conditions. The chips support input voltages from 2.95 V to 20 V and provide adjustable output voltages with high efficiency across a range of switching frequencies.
Detailed electrical characteristics, efficiency curves, thermal data, and package dimensions for MSOP and LFCSP variants are presented. Guidance on layout, such as connecting the exposed pad to ground, and compliance information (JEDEC standards) are also included. This manual is written in Chinese.
