LT8624SAV#PBF

Overview

The LT8624SAV#PBF is a synchronous step-down DC/DC converter from the Silent Switcher 3 family, manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7 V to 42 V and delivers up to 4 A output current. The device features integrated precision capacitors for low EMI and supports switching frequencies between 200 kHz and 3 MHz. It provides adjustable output voltages starting from 0.97 V and includes thermal regulation and cycle-by-cycle current limiting. Packaged in a 24-lead LQFN (4x4 mm) with exposed pad, it is rated for automotive applications within a junction temperature range of -40°C to 150°C.

Feature Summary

Silent Switcher 3 technology integrates precision capacitors to minimize high-frequency radiated emissions without external snubbers.
Supports wide input voltage ranges suitable for 12 V, 24 V, and 48 V industrial systems.
Features fast transient response capabilities to maintain stability under dynamic load conditions.

Applications

Industrial automation controllers
Automotive infotainment and sensor power supplies
Telecommunications base station equipment

Procurement Notes

Verify the specific suffix 'AV' against the official datasheet to confirm automotive qualification status and operating temperature ratings. Ensure the package marking matches the 24-LQFN specification. Cross-reference the manufacturer's latest documentation for any pinout revisions or RoHS compliance updates prior to final procurement.

Selection Notes

Select this component when designing for environments requiring strict electromagnetic interference limits alongside high efficiency. The integrated capacitor solution reduces board space requirements compared to traditional buck converters. Consider the 3 MHz maximum frequency option if smaller passive components are desired for the design.

Part Context

This part belongs to the LT8624S family of Silent Switcher 3 regulators. It shares architectural similarities with other members of the series but is distinguished by its specific automotive-grade qualification and thermal performance characteristics. The family emphasizes compact form factors and ease of layout due to the internal noise suppression components.
