LT8570EDD#PBF

Overview

The LT8570EDD#PBF is a PWM DC/DC converter from Analog Devices Inc., housed in an 8-DFN (3x3) package. It features a 65V switch capable of handling up to 400mA output current. The device supports Boost, Inverting, and SEPIC topologies with an adjustable output voltage range from 1.204V to 65V. Input voltage operates between 2.55V and 40V. Key electrical parameters include a typical quiescent current of 1µA and a switching frequency of 1.5MHz. It functions within a junction temperature range of -40°C to +125°C.

Feature Summary

Supports multiple conversion topologies including boost, inverting, and SEPIC configurations.
Features a high-voltage 65V power switch for flexible input and output voltage ranges.
Offers low quiescent current operation to enhance efficiency in standby modes.
Includes shutdown functionality for power management control.

Applications

Inverting converters generating negative voltages from positive inputs
Boost converters for stepping up lower input voltages
SEPIC converters for applications requiring input voltage variation

Procurement Notes

Verify the specific suffix and tape/reel or tube packaging details against the manufacturer's latest datasheet before ordering. Confirm that the 8-DFN footprint matches your PCB layout requirements. Ensure compatibility with the required thermal dissipation characteristics for your operating environment. Cross-reference the part number with official Analog Devices distributors to avoid counterfeit components.

Selection Notes

Select this component when a single IC needs to support multiple DC/DC topologies such as boost, inverting, or SEPIC. It is suitable for designs requiring a 65V switch rating and adjustable output voltages up to 65V. Consider the 400mA switch current limit and 1.5MHz switching frequency for filter component sizing. Verify that the input voltage range of 2.55V to 40V aligns with your system power rails.
