The LT8648SJV#PBF from Analog Devices is a high-performance synchronous step-down switching regulator. It utilizes the second generation Silent Switcher architecture, designed to significantly reduce EMI emissions, making it suitable for noise-sensitive applications. This design minimizes PCB layout sensitivity and integrates input and boost capacitors for optimized current loops.
Key electrical specifications include a wide input voltage range from 3V to 42V and a maximum output current of 15A. The device operates with a programmable switching frequency between 200kHz and 2.2MHz. It achieves high efficiency, reaching up to 95.5% at 1MHz and 93% at 2MHz under specific conditions. The regulator features a fast minimum switch on-time of 25ns, enabling high step-down ratios. Burst Mode operation allows for low quiescent current consumption, down to 100µA.
The LT8648SJV#PBF is available in a 36-lead LQFN (7x4mm) package and a 36-TFQFN exposed pad package, both designed for surface mounting. The exposed pad on the LT8648SP variant can be used for heat sink attachment to improve thermal performance. The operating temperature range is -40°C to 150°C (TJ).
