LTC3308BEV#TRMPBF

Voltage Regulators - DC DC Switching Regulators Overview

The LTC3308BEV#TRMPBF is a synchronous step-down DC/DC converter from Analog Devices, featuring Silent Switcher technology. It operates with an input voltage range of 2.25 V to 5.5 V and provides a single adjustable output between 500 mV and 5.5 V. The device delivers up to 4 A of output current at a fixed switching frequency of 2 MHz. It utilizes a 12-lead LQFN (2 mm x 2 mm) package for compact surface-mount installation. Quiescent current is specified at 40 uA, and the junction temperature range spans from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates Silent Switcher architecture to minimize radiated electromagnetic interference without requiring external ferrite beads or shielded inductors.
• Features synchronous rectification for high efficiency across wide load ranges.
• Supports adjustable output voltage via external resistor divider within the specified operational limits.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered equipment requiring low noise power rails
• Industrial control systems operating within standard voltage ranges
• Embedded computing modules needing compact power solutions

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging configuration. Confirm that the BEV grade meets required thermal and electrical specifications for the target environment. Ensure compatibility with moisture sensitivity level requirements during assembly processes. Cross-reference official datasheets for any recent manufacturing changes or obsolescence notices prior to final procurement decisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single output rail is sufficient and space constraints necessitate a 2 mm x 2 mm footprint. Consider the 2 MHz switching frequency for balancing component size against transient response needs. Evaluate the 4 A current capability against peak load demands to ensure adequate thermal headroom within the LQFN package.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LTC3308 family of Silent Switcher regulators. It shares architectural similarities with other members like the LTC3308BHV but differs in output current capacity and pinout configuration. The BEV variant specifically denotes the commercial temperature grade and package style within the broader product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LTC3308BHV#TRMPBF offers dual outputs with lower current per channel. LTC3308AIV#TRMPBF provides automotive qualification with similar single-output specifications. Verify pin-to-pin compatibility and thermal performance before substituting.
