L6756DTR

Special Purpose Regulators Overview

The L6756DTR is a two-to-four phase buck controller designed for low-voltage, high-current power supplies and Intel processor applications. It features LTB Technology for fast load transient response and an adjustable oscillator from 100 kHz to 1 MHz. The device supports programmable output voltage up to 1.6000 V with ±0.5% accuracy and includes feedback disconnection protection. It operates in a VFQFPN 6x6 mm package.

Special Purpose Regulators Feature Summary

• LTB Technology enhances load transient response
• Integrated remote sense buffer
• LSLess startup for pre-biased outputs
• Full-differential current sense across DCR

Special Purpose Regulators Applications

• Intel VR10 processor power supplies
• Intel VR11.x processor power supplies
• Low-voltage high-current power supplies

Special Purpose Regulators Procurement Notes

Verify the component status as the L6756D series is listed as obsolete in available records. Confirm availability of the specific L6756DTR suffix variant through authorized distributors or secondary market suppliers. Ensure compatibility with existing design infrastructure before procurement due to potential end-of-life constraints.

Special Purpose Regulators Selection Notes

Select this controller for designs requiring scalable two-to-four phase operation and precise voltage regulation. The integrated DAC supports Intel VR10 and VR11 standards. Consider the VFQFPN 6x6 mm package size for space-constrained layouts. Verify thermal management requirements for high-current applications.

Special Purpose Regulators Part Context

The L6756D belongs to STMicroelectronics' portfolio of advanced power management controllers. It is part of the broader family of solutions targeting high-performance computing and server applications. The device integrates multiple protection features and flexible driver support to simplify system design.

Special Purpose Regulators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the L6756D series is marked obsolete, alternative components must be identified based on functional equivalence and pin compatibility through independent engineering analysis.
