LT8622SAV#PBF

Overview

The LT8622SAV#PBF is an 18V, 2A synchronous step-down Silent Switcher 3 regulator from Analog Devices. It features a switching frequency range of 300kHz to 6MHz and supports surface mount installation in an SSOP-24 package. The device operates within a temperature range of -40°C to 125°C and includes a precision reference with ±0.8% accuracy over temperature. Output voltage ranges from 0V to (PVIN - 0.5V), delivering up to 2A continuous output current.

Feature Summary

Silent Switcher 3 architecture for ultralow EMI emissions
Ultralow RMS noise of 4μVRMS between 10Hz and 100kHz
Ultralow spot noise of 4nV/√Hz at 10kHz
Precision reference with remote sense capability

Applications

Industrial control systems requiring low noise power
Medical equipment sensitive to electromagnetic interference
Communication infrastructure power supplies
Test and measurement instrumentation

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm the SSOP-24 package availability matches your PCB footprint requirements. Ensure the 18V input rating aligns with your system's maximum supply voltage. Check for lead-free compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when ultralow noise and EMI are critical constraints alongside high efficiency. The Silent Switcher 3 technology eliminates the need for external shielding in many applications. Consider the 300kHz to 6MHz adjustable frequency range for optimizing inductor size versus transient response. Verify thermal performance under maximum load conditions given the 2A output capability.

Part Context

This part belongs to the LT8622 family of Silent Switcher regulators designed for demanding noise-sensitive applications. It integrates high-side and low-side MOSFETs with a proprietary layout technique to cancel magnetic fields. The AV suffix denotes the specific SSOP-24 package variant optimized for compact designs.
