LT8620IUDD#PBF

Overview

The LT8620IUDD#PBF is a synchronous monolithic step-down switching regulator from Analog Devices, housed in a 16-lead DFN package. It supports an input voltage range of 3.4 V to 65 V and delivers up to 2 A of continuous output current. The device features adjustable output voltages from 970 mV to 64.75 V with a typical quiescent current of 2.5 µA in Burst Mode operation. Operating frequencies are programmable between 200 kHz and 2.2 MHz. It functions within a temperature range of -40°C to +125°C.

Feature Summary

Integrates high-efficiency top and bottom power switches with all necessary control circuitry on a single die.
Utilizes Burst Mode operation to maintain ultra-low quiescent current for extended battery life in always-on systems.
Features a fast 30 ns minimum switch on-time enabling high-frequency constant frequency switching.
Includes internal compensation, soft-start, tracking, and precise enable pin thresholds.

Applications

Automotive single-battery and dual-battery systems
Industrial applications requiring wide input voltage ranges
GSM power supplies

Procurement Notes

Verify the specific suffix 'D' indicates the DFN package variant distinct from MSOP or QFN options. Confirm the 'I' grade meets the required -40°C to +125°C operating temperature range for your application environment. Cross-reference the datasheet revision to ensure compatibility with design-in requirements.

Selection Notes

Select this component when a compact solution is needed for high-voltage inputs up to 65 V. The DFN package offers thermal advantages over other form factors. Ensure the external inductor selection supports the 2 A current limit while maintaining saturation margins under overload conditions.

Part Context

This part belongs to the LT8620 series of synchronous buck regulators designed for efficiency and low standby power. It shares functional similarities with the LT8620HMSE and LT8620MPMSE but differs in package type and potentially thermal characteristics defined by the DFN footprint.
