LT3503EDCB#TRPBF

Overview

The LT3503EDCB#TRPBF is a synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6 V to 20 V and delivers a maximum output current of 1 A. The device integrates a 2.2 MHz switching frequency, allowing for the use of small external components. It features adjustable output voltage capability and includes internal soft-start functionality to limit inrush current. The component is housed in a DFN-6 package and is designed for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-efficiency synchronous buck regulator topology
• Includes internal soft-start circuitry to manage startup transients
• Supports adjustable output voltage configurations via external resistors

Applications

• Portable battery-powered equipment requiring efficient power conversion
• Industrial control systems utilizing single-supply architectures
• Embedded applications with strict space constraints due to compact packaging

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when placing orders. Confirm that the E-grade temperature rating aligns with your operational environment requirements. Ensure compatibility with the DFN-6 footprint during PCB layout. Cross-reference the manufacturer's latest datasheet for any updates regarding pinout or electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when a compact solution is needed for converting higher voltages down to lower logic levels. The 2.2 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 1 A output limit against peak load demands. Evaluate the thermal performance within the DFN-6 package for your specific ambient conditions. This part is suitable for designs prioritizing efficiency and board space over ultra-low quiescent current.
