LT3480IDD#PBF

Overview

The LT3480IDD#PBF is a monolithic synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6V to 36V and delivers up to 2A of output current. The device features an adjustable switching frequency from 200kHz to 2.4MHz and maintains a quiescent current of 70µA at 12VIN to 3.3VOUT. It utilizes Burst Mode operation for low ripple and high efficiency at light loads, with output voltages adjustable between 0.79V and 20V. The component is housed in a 10-lead DFN package.

Feature Summary

Integrates a 0.25Ω saturating switch and boost Schottky diode for high efficiency
Supports adjustable switching frequencies from 200kHz to 2.4MHz
Features low ripple Burst Mode operation for improved light-load performance
Includes power good flag and controlled soft-start capability

Applications

Automotive battery regulation
Power supplies for portable products
Distributed supply regulation systems
Industrial power supplies

Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm package type and temperature rating. Ensure compatibility with required thermal management solutions for the DFN-10 package. Confirm RoHS compliance status through manufacturer datasheets prior to integration into final designs.

Selection Notes

Select this component when designing buck converters requiring wide input voltage ranges up to 36V and high peak currents of 2A. The adjustable frequency feature allows optimization for size or noise constraints. Consider the exposed pad requirement for thermal dissipation in the DFN package during PCB layout planning.

Part Context

This part belongs to the LT3480 family of micropower switching regulators designed for applications demanding high efficiency across varying load conditions. The IDD suffix indicates a specific pin-compatible variant within the broader product line, sharing core electrical characteristics with other packages like MSOP while offering distinct thermal properties.
