LT8570EDD-1#PBF

Overview

The LT8570EDD-1#PBF is a PWM DC/DC converter from Analog Devices Inc., housed in an 8-WFDFN package with exposed pad. It integrates a 0.25A, 65V power switch and supports Boost, SEPIC, Cuk, and Inverting topologies. The device accepts an input voltage range of 2.55V to 40V and provides an adjustable output from 0.003V to 65V (switch rating). It operates at a switching frequency between 200kHz and 1.5MHz, delivering up to 375mA switch current. The component functions within a junction temperature range of -40°C to 125°C.

Feature Summary

Integrates a high-voltage 65V power switch capable of handling transient voltages.

Applications

Inverting converters generating negative outputs from positive inputs
Boost converters for step-up voltage regulation
SEPIC converters for wide input voltage ranges

Procurement Notes

Verify the specific suffix 'EDD-1' against the manufacturer datasheet to confirm pinout and internal configuration differences compared to standard LT8570 variants. Ensure the 8-WFDFN footprint matches the PCB design requirements. Confirm RoHS compliance status through official documentation before finalizing procurement orders.

Selection Notes

Select this part when a compact solution is required for applications needing both positive and negative output capabilities or wide input ranges. The integrated 65V switch allows operation with higher input voltages without external protection components. Consider the thermal performance of the DFN package for heat dissipation needs in enclosed environments.

Part Context

This component belongs to the LT8570 family of versatile DC/DC converters designed for space-constrained designs. The '-1' suffix typically denotes specific internal configurations or pinouts distinct from the base model. It serves as a flexible building block for various power conversion architectures requiring high voltage tolerance.
