The Intel Enpirion® ER3125QI is a highly versatile buck-boost switching regulator IC designed for efficient power conversion. This component offers an adjustable positive output voltage ranging from 0.5V up to 36V, capable of delivering a continuous output current of 2.5A. Its innovative topology supports both step-down and step-up/step-down (buck-boost) operation, maximizing efficiency across a wide input voltage range of 3V to 36V. The ER3125QI features a broad switching frequency range from 200kHz to 2.2MHz, allowing for optimized design trade-offs between component size and efficiency. With integrated synchronous rectification, this device achieves high power conversion efficiency. Housed in a 20-VFQFN exposed pad package, it is suitable for surface mount applications and operates across an industrial temperature range of -40°C to 105°C. This regulator is widely utilized in power management solutions for networking, computing, and industrial equipment.
