LTC3308AIV#TRPBF

Voltage Regulators - DC DC Switching Regulators Overview

The LTC3308AIV#TRPBF is a synchronous step-down DC/DC converter from Analog Devices, featuring Silent Switcher technology. It operates with an input voltage range of 2.25V to 5.5V and delivers up to 4A output current. The adjustable output voltage spans from 500mV to 5.5V. Integrated into a compact 12-LQFN (2mm x 2mm) package, the device supports a fixed switching frequency of 2MHz. It functions reliably across an extended junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Silent Switcher architecture minimizes radiated electromagnetic interference without external snubbers
• Integrated high-side and low-side N-channel power switches for efficient synchronous rectification
• Compact 2mm x 2mm LQFN-12 package facilitates dense PCB layout
• Fixed 2MHz switching frequency enables the use of small passive components

Voltage Regulators - DC DC Switching Regulators Applications

• Battery-powered portable equipment requiring low noise power rails
• Industrial control systems needing robust power management in compact enclosures
• Automotive infotainment and instrumentation modules
• Communication infrastructure boards with strict EMI constraints

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the A-grade temperature rating matches system requirements. Check current availability status as supply may be limited. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate that the 12-LQFN footprint aligns with existing board designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when space is constrained and EMI performance is critical. The 4A current capability suits moderate load applications. Consider the 2MHz frequency trade-off between size and efficiency. Verify input voltage stability within the 2.25V to 5.5V window. Compare against non-Silent Switcher alternatives if cost is the primary driver over noise performance.

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 devices in the series but differs in current rating and package options. The IV suffix denotes the industrial temperature grade and specific package variant. It complements Analog Devices' portfolio of high-efficiency PMIC solutions for space-sensitive designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LTC3308 variants such as LTC3308BHV#TRMPBF for dual-output needs or different current ratings. Non-Silent Switcher equivalents like the LTC3306 offer similar electrical specs but lack integrated EMI filtering. Verify pin compatibility and thermal characteristics before swapping packages.
