Overview
Description
LTC3219EUD#TRPBF is a Linear Technology/Analog Devices DC-DC buck regulator (LTC3219 family). The EUD suffix designates a specific package variant, and #TRPBF indicates Tape & Reel Pb-free packaging. The device provides high-efficiency step-down conversion from a higher input to a user-set output rail, with features such as enable control, soft-start, protection (overcurrent/thermal), and precise regulation via feedback. It is intended for compact point‑of‑load power supplies in telecom, industrial, automotive, and other applications where size and efficiency matter. For exact electrical specs (input range, output voltage options, switching frequency, current capability) you should consult the LTC3219 datasheet and the datasheet for the EUD package variant to confirm pinout, performance, and packaging details.
Pinout
