概述
Description
LT1910ES8#PBF is an 8‑pin Linear Technology (now Analog Devices) device used as a high‑voltage, constant‑current regulator/LED driver. The ES8 suffix indicates the 8‑lead MSOP package, and PBF means Pb‑free. The IC provides a control loop that senses current (via a sense resistor) and regulates load current, suitable for driving LEDs or other constant‑current loads from a higher supply. It typically requires an external power device (transistor) and external resistors to set the programmable current, with protections such as enable control, current/short‑circuit protection, undervoltage, and thermal shutdown. Applications include automotive lighting, LED backlighting, and compact constant‑current Regulators. For exact pinout, configuration, and electrical specs (input voltage range, current set resistor, protection thresholds, etc.), refer to the LT1910 datasheet on Analog Devices’ website.
