LTC3872HTS8#TRPBF

DC DC Switching Controllers Overview

The LTC3872HTS8#TRPBF is a synchronous step-up DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.75V to 9.8V and supports output voltages up to 60V with a maximum current capability of 2A. The device utilizes a fixed 550kHz switching frequency and features a low quiescent current of 250µA. Packaged in an 8-lead TSOT-23, it includes integrated soft-start and cycle-by-cycle current limiting for robust performance across industrial temperature ranges.

DC DC Switching Controllers Feature Summary

• Eliminates the need for external sense resistors through proprietary current mode control architecture
• Integrates high-side and low-side gate drivers for efficient synchronous rectification
• Provides programmable soft-start functionality to limit inrush current during startup
• Includes cycle-by-cycle current limiting to protect against short circuits and overloads

DC DC Switching Controllers Applications

• Battery-powered portable equipment requiring efficient voltage boosting
• Industrial systems utilizing single-cell lithium-ion or alkaline battery sources
• Automotive electronics operating from 12V or 24V nominal bus lines
• Telecommunications infrastructure power distribution modules

DC DC Switching Controllers Procurement Notes

Verify the specific suffix HTS8 corresponds to the required temperature grade and package variant when ordering. Confirm RoHS compliance status via the manufacturer's latest documentation. Ensure compatibility with the intended PCB footprint for the TSOT-23-8 package. Cross-reference the datasheet revision date to validate all electrical specifications against your design requirements before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component for designs prioritizing minimal external component count due to the absence of current sense resistors. It is suitable for applications requiring high efficiency at moderate load currents up to 2A. Consider the 550kHz fixed frequency for EMI management and passive size optimization. Evaluate the 250µA supply current against standby power constraints in battery-operated devices.

DC DC Switching Controllers Part Context

This part belongs to the LTC3872 family of synchronous boost controllers designed for high-efficiency power conversion. It shares architectural similarities with other members like the LTC3872ETS8 but may differ in thermal or electrical grading. The family targets compact power solutions where board space is limited. Development is supported by evaluation boards such as the DC989B series for performance validation.

DC DC Switching Controllers Replacement Considerations

The LTC3872ETS8#TRPBF is a verified alternative within the same product family. Verify that the pinout and electrical characteristics remain identical for direct substitution. Check for any differences in operating temperature ranges or package tolerances between the HTS8 and ETS8 suffixes.
