PAM2861CBR-A Equivalent & Substitute Parts Engineering Reference

Part Overview

The PAM2861CBR-A, manufactured by Diodes Incorporated, is an LED driver IC designed for step-down (buck) DC-DC regulation with PWM dimming capability. It supports a single output with up to 1A current, operates within a supply voltage range of 6V to 40V, and is housed in a SOT-89-5 package for surface mount applications. The product status is obsolete, making it necessary to identify suitable alternatives to maintain BOM integrity and ensure continued production or support for equipment using this component.
