LTC3827IG-1#TRPBF

DC DC Switching Controllers Overview

The LTC3827IG-1#TRPBF is a low quiescent current, dual-phase synchronous step-down controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4V to 36V and supports output voltages from 800mV to 10V. The device features a fixed switching frequency of 400kHz with a maximum duty cycle of 99%. Designed for high-efficiency power delivery, it drives external N-channel MOSFETs to support load currents up to 25A per phase. The component functions within a temperature range of -40°C to +85°C and is housed in a 28-pin SSOP package.

DC DC Switching Controllers Feature Summary

• Dual-phase architecture enables interleaved operation for reduced input and output ripple currents while increasing effective switching frequency.
• Low quiescent current consumption ensures high efficiency during light-load conditions and standby modes.
• Integrated synchronous rectification drivers eliminate the need for external Schottky diodes, improving overall converter efficiency.
• Supports precise tracking and sequencing capabilities through dedicated control pins for multi-rail system management.

DC DC Switching Controllers Applications

• Point-of-load regulation for industrial equipment and telecommunications infrastructure
• Power distribution systems requiring multiple independent voltage rails
• Embedded computing platforms needing efficient buck conversion from higher bus voltages

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging when sourcing. Confirm RoHS compliance status directly with the manufacturer or authorized distributors as regulatory requirements may vary by region. Ensure the ordering part number matches the exact pinout and thermal characteristics required for the target PCB layout design.

DC DC Switching Controllers Selection Notes

Select this controller when designing dual-phase buck converters requiring low static current and wide input voltage ranges. It is suitable for applications where space constraints favor surface-mount SSOP packages over larger QFN options. Consider external component ratings for voltage and current handling to match the controller's 25A per phase capability.

DC DC Switching Controllers Part Context

This component belongs to the LTC3827-1 series of PolyPhase controllers. It shares functional similarities with other devices in the family but differs in package type and specific electrical parameters. The IG-1 variant specifically denotes the SSOP-28 package configuration, distinguishing it from QFN-based counterparts like the EUH or IUH series.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LTC3827EUH#TRPBF and LTC3827IUH#TRPBF, which offer identical electrical performance but utilize different package footprints. Designers must account for mechanical differences and potential thermal dissipation variations when swapping between SSOP and QFN versions.
