These parts are in production but have been determined to be LAST TIME BUY. The A8514 is a multi-output white LED driver for small LCD backlighting, integrating a boost converter with internal switch and four current sinks (up to 320mA). It operates from 5V to 40V, supports external P-FET input disconnect, offers comprehensive protection, and features a synchronization pin for AM radio band avoidance.
