概要
Description
LTC1760CFW#PBF is a Linear Technology (Analog Devices) part number for the LTC1760 buck regulator in a Pb-free variant. Key points:
- “CFW” is the internal package/footprint code used by Linear Tech to designate a specific physical package for the LTC1760.
- “#PBF” indicates Pb-free (lead-free) and RoHS-compliant packaging.
- Function: LTC1760 is a high-efficiency DC-DC step-down regulator (needs external inductor, diode or switch, and capacitors per datasheet). It typically offers adjustable output, enable control, soft-start, and current-mode or related features depending on variant.
For exact pinout, package dimensions, and electrical specs, refer to the LTC1760 datasheet and the packaging table for the CFW#PBF variant.
