LT8711EUDC#PBF

Overview

The LT8711EUDC#PBF is a multi-topology current mode PWM controller from Analog Devices Inc. It supports synchronous buck, boost, SEPIC, and ZETA configurations. The device operates with a supply voltage range of 4.5V to 42V and features an adjustable switching frequency between 100kHz and 750kHz. It utilizes a 20-WFQFN exposed pad package and functions within a temperature range of -40°C to 125°C.

Feature Summary

• Supports multiple power conversion topologies including synchronous buck, boost, SEPIC, and ZETA.
• Integrates current mode PWM control for precise regulation.
• Features clock synchronization capability for system noise reduction.

Applications

• Industrial power supplies
• Telecommunications equipment
• Automotive electronics

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature grade. Confirm availability status as product lifecycles may change. Ensure compatibility with existing board layouts when substituting components.

Selection Notes

Select this component for designs requiring flexible topology configuration in a compact footprint. Evaluate thermal performance requirements given the QFN package. Verify input voltage constraints align with the 42V maximum limit.

Part Context

This part belongs to the LT8711 family of multi-topology controllers. It shares functional similarities with other Linear Technology derived PMICs but offers distinct flexibility in circuit configuration compared to single-function regulators.

Replacement Considerations

LT8711IUDC#PBF is listed as a direct substitute. Verify pinout and electrical specifications match before implementation.
