LT8570HDD#TRPBF

Overview

The LT8570HDD#TRPBF is a monolithic switching regulator IC manufactured by Analog Devices Inc., designed for boost, SEPIC, and inverting DC/DC converter topologies. It features an integrated 65V switch capable of delivering up to 375mA of output current. The device operates with an input voltage range from 2.55V to 40V and supports adjustable output voltages starting from 1.204V. It includes a programmable switching frequency ranging from 200kHz to 1.5MHz and offers positive or negative output configurations within an 8-lead WDFN package.

Feature Summary

Supports multiple topologies including boost, SEPIC, and inverting configurations for flexible power conversion.
Integrates a high-voltage 65V switch to handle wide input voltage ranges.
Features adjustable switching frequency synchronization capabilities.

Applications

Battery-powered systems requiring voltage step-up or inversion
Industrial control circuits utilizing SEPIC topology
Negative rail generation for analog signal processing

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the exact part number against official Analog Devices documentation to ensure compatibility with design requirements. Check for RoHS compliance status as indicated in the manufacturer's material declaration. Validate that the 8-WFDFN package dimensions match your PCB footprint specifications before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring a compact solution for boost, SEPIC, or inverting applications with inputs up to 40V. Consider the 375mA switch current limit and the 65V voltage rating for appropriate load matching. Evaluate the need for external compensation components based on the chosen switching frequency and topology configuration.

Part Context

This component belongs to the LT8570 family of switching regulators, which are engineered for high-efficiency power management in space-constrained designs. The LT8570 series provides versatile topology options within a small footprint, catering to applications needing reliable voltage conversion from single-cell or multi-cell battery sources.
