LT8636HV#PBF

Overview

The LT8636HV#PBF is a synchronous step-down Silent Switcher regulator from Analog Devices, housed in an LQFN-20 package. It supports input voltages from 3.4 V to 42 V and delivers up to 5 A output current with adjustable voltage. The device features a low quiescent current of 1.7 uA and operates at switching frequencies between 200 kHz and 3 MHz. It functions within a temperature range of -40°C to +150°C.

Feature Summary

• Integrates Silent Switcher architecture to minimize electromagnetic interference radiation without external components.
• Provides high efficiency across wide load ranges through synchronous rectification.
• Supports flexible design options via adjustable switching frequency and programmable soft-start.

Applications

• Industrial automation power supplies
• Distributed power systems
• Point-of-load regulation

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and thermal characteristics. Confirm RoHS compliance status for your region. Check for moisture sensitivity level requirements during storage and handling. Ensure the LQFN-20 footprint matches your PCB layout guidelines precisely before ordering.

Selection Notes

Select this component when high input voltage capability up to 42 V is required alongside significant output current. Consider the LQFN-20 package for compact designs needing robust thermal performance. Evaluate the 200 kHz to 3 MHz frequency range against EMI constraints and inductor size requirements.

Part Context

This part belongs to the LT8636 family of Silent Switcher regulators designed for demanding industrial applications. It shares architectural similarities with other high-voltage buck converters but offers specific current and voltage ratings tailored for dense power delivery solutions.
