LTC3736EUF#PBF

DC DC Switching Controllers Overview

The LTC3736EUF#PBF is a dual-phase, no current sense resistor synchronous buck controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.75V to 9.8V and supports switching frequencies between 300kHz and 750kHz. The device features a 0.6V ±1% voltage reference and offers 100% duty cycle operation for low dropout applications. Packaged in a 24-lead QFN (4mm x 4mm) with an exposed pad, it includes integrated soft-start, power good monitoring, and micropower shutdown capabilities drawing only 9μA. The controller supports output tracking and selectable pulse-skipping or forced continuous modes.

DC DC Switching Controllers Feature Summary

• Eliminates the need for current sense resistors through proprietary sensing technology
• Provides out-of-phase dual phase control to minimize required input capacitance
• Integrates a tracking function for synchronized multi-rail power sequencing
• Supports true PLL frequency locking or external clock adjustment

DC DC Switching Controllers Applications

• Point-of-load regulation for high-density server and workstation architectures
• Power management systems requiring minimal component count and board space
• Multi-output power supplies utilizing output voltage tracking capabilities
• Portable electronics demanding extended battery life via micropower shutdown

DC DC Switching Controllers Procurement Notes

Verify the specific suffix designation when ordering, as package type and tape/reel specifications vary between EUF and TRPBF variants. Confirm that the requested part matches the exact pinout and thermal pad requirements for your PCB layout. Cross-reference the manufacturer's latest datasheet revision to ensure compatibility with your design constraints. Validate RoHS compliance status directly with the supplier documentation prior to final procurement approval.

DC DC Switching Controllers Selection Notes

Select this controller for designs prioritizing efficiency and size reduction by removing current sense components. Ensure the application input voltage remains strictly within the 2.75V to 9.8V operational window. Consider the 24-QFN package dimensions for thermal management and footprint planning. Evaluate the need for output tracking if multiple rails require coordinated startup sequences.
