Description and Introduction
8-Bit Programmable 2- to 5-Phase Synchronous Buck Controller The ADP3189JCPZ-RL is a voltage regulator controller manufactured by Analog Devices (AD). It is designed for use in high-performance, multi-phase synchronous buck converter applications. The part is specified as Pb-free, meaning it complies with the Restriction of Hazardous Substances (RoHS) directive, which restricts the use of lead and other hazardous materials in electronic components. The "RL" suffix typically indicates that the part is supplied in tape and reel packaging for automated assembly processes.
