The 14-SO package is a standard footprint shared by many Linear Technology / Analog Devices power controllers, so the board layout is straightforward. Supplied in tube — if your pick-and-place line prefers tape, confirm the reel option at quote time. ## Lifecycle and sourcing posture Listed as Active with ROHS3 compliance. For dual-source planning, the closest functional peer is the LTC1148CS#PBF: same buck controller, same 14-SOIC package, same 0°C to 70°C temperature grade, same synchronous rectification and 250 kHz switching ceiling. The LTC1148CS#PBF is a validated second source for the same BOM footprint.","metaTitle":"LTC1148LCS-3.3#PBF Buck Controller, 250kHz, 14-SOIC","metaDescription":"LTC1148LCS-3.3#PBF step-down buck controller from Analog Devices.
