Switching Controllers (External Switches)

Description

Switching controllers offer flexibility to set output current level and limits ranging from zero to > 5 A for asynchronous designs and > 20 A channel for synchronous designs. Controller based switching regulators provide highest efficiency and performance that can be tailored to the application's requirements. Available features include single and dual channels, enable, softstart, UVLO, current limit, margining, tracking, frequency synchronization, 3 V to 24 V input voltage range, power good flag, and output accuracy to 0.5% accuracy 25°C.

Design Tools Online ADIsimPower Design Tool produces ready-to-go ADP1864 switching controller designs optimized for efficiency, space, cost, or part count. Change IC Selection to enable the ADP1864 designs.

Download ADP1864 Design Software is similar to the online ADIsimPower but as an Excel application.
