LTC3260IDE#TRPBF

Overview

The LTC3260IDE#TRPBF is a wide input voltage range buck-boost charge pump featuring an integrated watchdog timer. Manufactured by Analog Devices Inc., this component operates within a supply voltage range of 4.5V to 32V and delivers a maximum output current of 100mA. It supports adjustable output voltages with a switching frequency range of 50kHz to 500kHz. The device is housed in a 16-MSOP-EP package with exposed pad, suitable for surface mount installation. It functions as a single-output regulator designed for applications requiring reliable bias generation across varying input conditions.

Feature Summary

• Integrates a watchdog timer for enhanced system reliability and fault monitoring
• Supports wide input voltage ranges from 4.5V to 32V for flexible power architectures
• Provides low noise performance suitable for sensitive analog circuitry
• Offers adjustable output voltage capability via external components

Applications

• Bias generation for operational amplifiers and data converters
• Power management in industrial control systems
• Supply regulation for sensor interfaces
• Negative voltage generation for mixed-signal circuits

Procurement Notes

Verify the specific suffix 'IDE' against official Analog Devices documentation to confirm temperature grade and packaging specifications. Confirm RoHS compliance status through the manufacturer's latest material declaration. Ensure the 16-MSOP-EP footprint matches your PCB design requirements. Cross-reference the datasheet revision date to validate electrical characteristics before finalizing procurement decisions.

Selection Notes

Select this component when a wide input voltage range and integrated fault protection are required. The inclusion of a watchdog timer distinguishes it from standard charge pumps. Consider the 100mA output limit and 50kHz to 500kHz frequency range for filtering requirements. The exposed pad package necessitates adequate thermal relief on the printed circuit board for optimal heat dissipation during operation.

Part Context

This part belongs to the LTC3260 family of wide VIN range buck-boost charge pumps. It is designed to provide stable bias voltages regardless of input fluctuations. The device integrates high-efficiency switching elements and control logic into a compact surface-mount package. It serves as a critical power management solution for applications demanding robust voltage regulation without external complex controller circuits.

Replacement Considerations

Consult Analog Devices documentation for direct pin-compatible substitutes within the LTC3260 series. Verify functional equivalence regarding watchdog timer implementation and output current capabilities. Check for updated package variants or improved thermal performance options available from the manufacturer.
