LTC3736EUF#TRPBF

DC DC Switching Controllers Overview

The LTC3736EUF#TRPBF is a dual synchronous step-down switching controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.75V to 9.8V and provides two independent outputs adjustable from 600mV to 9.8V. The device supports up to 5A output current per channel with a fixed switching frequency of 750kHz. It features a low quiescent current of 9µA in shutdown mode and includes internal soft-start, power good monitoring, and output tracking capabilities. Packaged in a 24-lead QFN (4mm x 4mm) for surface mount applications.

DC DC Switching Controllers Feature Summary

• Eliminates the need for current sense resistors through integrated no-RSENSE control architecture
• Provides out-of-phase operation between two phases to minimize required input capacitance
• Includes an output tracking function allowing synchronized voltage ramping between channels

DC DC Switching Controllers Applications

• Point-of-load regulation for high-performance processors
• Data acquisition systems requiring precise voltage sequencing
• Industrial equipment power distribution networks

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with external MOSFET selection based on the 750kHz switching frequency. Confirm that the application circuit design accounts for the specific thermal requirements of the 24-QFN package during operation.

DC DC Switching Controllers Selection Notes

Select this component when designing dual-output buck converters requiring resistorless current sensing and tight output voltage tracking. It is suitable for applications needing wide input voltage ranges up to 9.8V and low standby power consumption. Consider the 24-QFN package constraints for PCB layout and thermal management compared to other PMIC options.

DC DC Switching Controllers Part Context

This part belongs to the LTC3736 family of dual synchronous controllers designed for efficient power delivery. It complements other Analog Devices regulators like the LTC3633 series by offering specialized tracking and no-sense features. The device is distinct from single-channel regulators and higher-voltage industrial controllers in the broader portfolio.

DC DC Switching Controllers Replacement Considerations

LTC3736EUF-1#TRPBF and LTC3736EUF-2#TRPBF are confirmed variants within the same family.
