LT8570IMS8E-1#PBF

Overview

The LT8570IMS8E-1#PBF is a PWM DC/DC converter from Analog Devices Inc., housed in an 8-MSOP package. It features an integrated 0.25A, 65V power switch and supports Boost, SEPIC, and Inverting topologies. The device operates with an input voltage range of 2.55V to 40V and delivers an adjustable output voltage between 1.204V and 65V. It offers a fixed switching frequency of 700kHz and draws a typical quiescent current of 1.2mA. The component functions within a junction temperature range of -40°C to +125°C.

Feature Summary

Configurable as a boost, SEPIC, or inverting converter for versatile power conversion needs
Integrates a 65V rated power switch capable of handling 0.25A continuous current
Supports wide input voltage ranges suitable for single-cell lithium battery applications

Applications

Generating negative supply rails from positive inputs
Boosting low input voltages to higher levels for system operation
Creating isolated or floating supplies using SEPIC configurations

Procurement Notes

Verify the specific suffix E-1 against the official datasheet to confirm the 700kHz fixed frequency variant. Ensure the MSOP-8 package matches the target PCB footprint. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.

Selection Notes

Select this component when a compact solution is required for boosting or inverting applications with moderate current demands. The fixed 700kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 0.25A limit when designing for load requirements exceeding this threshold.

Part Context

This part belongs to the LT8570 family of high-voltage PWM converters designed for space-constrained designs. It shares architectural similarities with other members like the LT8570EDD-1 but differs in package type and switching frequency specifications. The series targets portable electronics and industrial systems requiring efficient voltage translation.
