The LT8614IUDC#TRPBF is a high-performance step-down DC-DC switching regulator from Analog Devices, designed for applications requiring high efficiency and low EMI emissions. It features the Silent Switcher architecture, enabling operation at frequencies up to 3MHz while minimizing electromagnetic interference.
This regulator boasts a wide input voltage range of 3.4V to 42V and can deliver up to 4A of output current. A key feature is its ultralow quiescent current of 2.5µA in Burst Mode operation, making it suitable for applications with very small load currents. The output voltage ripple is kept below 10mVP-P across all load conditions.
The LT8614IUDC#TRPBF supports a fast minimum switch on-time of 30ns, allowing for high VIN to low VOUT conversions at high frequencies. It operates safely even with inductor saturation in overload conditions. The device is available in a compact 20-QFN (3x4mm) package with an exposed pad, suitable for surface mounting.
Essential features include an open-drain PG pin for output regulation signaling, a SYNC pin for clock synchronization and mode selection (Burst Mode or pulse-skipping), and a TR/SS pin for soft-start and tracking functionality. The EN/UV pin allows for an accurate enable threshold setting, and the RT pin programs the switching frequency.
