The LT8641IUDC#PBF from Analog Devices is a high-performance step-down switching regulator designed for applications requiring low EMI emissions and high efficiency. It utilizes a Silent Switcher architecture and operates at frequencies up to 3MHz.
Key electrical specifications include a wide input voltage range of 3V to 65V, a maximum continuous output current of 3.5A (5A peak transient), and an ultralow quiescent current of 2.5µA. The device offers excellent transient response and an output voltage ripple below 10mVp-p. It features a fast minimum switch on-time of 35ns and low dropout voltage under all conditions.
This regulator is assembled in a compact 3mm x 4mm QFN package, making it suitable for space-constrained designs. The operating temperature range is -40°C to 125°C (TJ). Essential features include an open-drain PG pin for output regulation signaling, and the SYNC/MODE pin for selecting operating modes and external synchronization.
Applications for the LT8641IUDC#PBF include automotive and industrial supplies, and general-purpose step-down conversion where high efficiency and low EMI are critical.
