LTC3260HMSE#PBF

Overview

The LTC3260HMSE#PBF is a monolithic charge pump voltage converter manufactured by Analog Devices Inc. It operates from a single supply voltage ranging from 4.5V to 32V and delivers a regulated negative output voltage. The device features an adjustable output current limit up to 100mA and supports switching frequencies between 50kHz and 500kHz. Packaged in a 16-lead MSOP with exposed pad, it is designed for industrial applications requiring a wide operating temperature range of -40°C to 150°C.

Feature Summary

• Integrates a high-efficiency charge pump topology for generating negative voltages from a single positive supply.
• Provides adjustable output current limiting to protect the device and load under fault conditions.
• Features a wide input voltage range suitable for various power bus architectures.
• Includes thermal shutdown protection to ensure reliability during overtemperature events.

Applications

• Biasing operational amplifiers and other analog circuits requiring dual supplies
• Powering RS-232 transceivers and interface drivers
• Providing negative rails for sensor signal conditioning
• Gate drive circuits for N-channel MOSFETs

Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the HMSE variant meets the extended industrial temperature range requirements. Ensure the 16-MSOP-EP footprint matches the PCB layout specifications. Check for any recent Production Change Notices regarding material or assembly updates.

Selection Notes

Select this component when a compact solution for generating negative voltage from a single positive rail is required. Consider the maximum output current capability and switching frequency range relative to external capacitor selection. Evaluate the thermal performance within the 16-MSOP package for the expected ambient temperature and load conditions.

Part Context

This part belongs to the LTC3260 family of charge pump converters. It shares core functionality with variants like the LTC3260EMSE#TRPBF, differing primarily in packaging type (tube vs. tape and reel) and potentially temperature grade. It serves as a PMIC solution for simple voltage inversion tasks.
