Tổng quan
Description
LTC7878AUH#TRPBF is Linear Technology/Analog Devices’ part number for the LTC7878 DC-DC regulator controller. It is a high-performance, multi‑phase (multichannel) PWM controller intended for building high‑current, synchronous buck regulators (VRMs) with external MOSFETs and inductors.
What the suffixes mean:
- AUH: a specific package/variant of the LTC7878 (package type shown in the datasheet).
- #TRPBF: tape-and-reel packaging, Pb-free (lead-free).
Use and notes:
- The device itself is a controller; you pair it with external power stages to implement a regulator.
- For exact electrical specs, package details, and application notes, consult the LTC7878 datasheet on Analog Devices’ website.
