It accepts a wide input range from 2.7V up to 28V, making it suitable for multi-rail systems derived from a 5V, 12V, or 24V supply bus. The 1.25MHz fixed switching frequency keeps external inductor and capacitor values small, shrinking the overall footprint. Synchronous rectification is built in, so no external catch diode is needed — that saves a component and a bit of board area. Typical applications include distributed power architectures, point-of-load regulation in telecom/networking gear, and battery-powered equipment where two regulated rails are required from a single controller. ## Package and rework considerations The MAX1774EEI+ comes in a 28-lead QSOP (0.154\" wide, 3.90 mm body width) — a narrow SOIC with a fine pitch. It is a surface-mount part, reworkable with a standard hot-air station. ## Lifecycle and sourcing This part is listed as Active with ROHS3 compliance. It remains a current-production item from Maxim Integrated (now part of Analog Devices). No end-of-life notice or last-time-buy window is in effect. For BOM planning, this means no forced redesign for obsolescence in the near term. The 28-QSOP package is standard and stocked across multiple channels, so lead times are generally manageable for production volumes.","metaTitle":"MAX1774EEI+ Dual Buck Regulator, 1.5A/2A, 28-QSOP","metaDescription":"MAX1774EEI+ dual step-down buck regulator: 2.7V-28V input, adjustable outputs, 1.5A/2A per channel, 1.25MHz switching, -40°C to +85°C.
