LTC3260HMSE#TRPBF

Overview

The LTC3260HMSE#TRPBF is a monolithic switching charge pump regulator manufactured by Analog Devices Inc. It operates from a 4.5V to 32V input supply and provides a single adjustable output capable of delivering up to 100mA. The device utilizes an internal oscillator with a frequency range of 50kHz to 500kHz. It is housed in a 16-lead MSOP package with an exposed thermal pad, designed for surface-mount installation. The component supports a junction temperature range from -40°C to 125°C.

Feature Summary

• Integrates a high-efficiency switching charge pump topology for voltage inversion or doubling applications
• Features an adjustable output voltage controlled via external feedback components
• Includes an internal oscillator allowing flexible switching frequency selection between 50kHz and 500kHz
• Designed with an exposed thermal pad to facilitate heat dissipation in compact surface-mount layouts

Applications

• Portable battery-powered equipment requiring negative rail generation
• Industrial control systems needing isolated or inverted power supplies
• Communication modules requiring dual polarity voltage rails
• Sensor interfaces utilizing pseudo-differential inputs with bipolar supply requirements

Procurement Notes

Verify the specific suffix designation upon procurement, as the provided model identifier contains a combination of attributes that may not align with standard manufacturer ordering codes. Confirm the packaging format matches project requirements, distinguishing between tube and reel configurations. Ensure the thermal pad connection is properly implemented on the PCB to maintain specified operating temperatures and electrical performance.

Selection Notes

Select this component when a compact solution for generating negative or doubled voltages from a single positive supply is required. Consider the 100mA output current limit and the 4.5V minimum input voltage constraint during circuit design. Evaluate the need for external frequency setting resistors if operation outside the default range is necessary. Assess thermal management requirements due to the power dissipation characteristics within the small MSOP footprint.
