LT8570HMS8E-1#PBF

Overview

The LT8570HMS8E-1#PBF is a PWM DC/DC converter manufactured by Analog Devices Inc., housed in an MSOP-8 surface-mount package. It features a 65V power switch capable of delivering up to 200 mA output current. The device supports Boost, SEPIC, and Inverting topologies with an input voltage range of 2.55 V to 40 V and an adjustable output voltage from 1.204 V to 65 V. Operating at a fixed 1.5 MHz switching frequency, it draws 1.2 mA of quiescent current. The component functions within a temperature range of -40°C to +125°C.

Feature Summary

Configurable as a boost, SEPIC, or inverting converter topology
Integrated 65V power switch for high-voltage applications
Fixed 1.5 MHz switching frequency operation

Applications

Boost converter configurations
SEPIC converter implementations
Inverting DC/DC conversion circuits

Procurement Notes

Verify the specific suffix E-1 against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the MSOP-8 package matches the target PCB footprint. Confirm that the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the part number with the latest product change notifications to ensure no manufacturing updates affect functionality.

Selection Notes

Select this component when a single-output regulator supporting multiple topologies is required. The 65V switch rating allows for high step-up ratios. Consider the 200 mA current limit for load requirements. The 1.5 MHz frequency enables smaller passive components compared to lower-frequency alternatives. Verify input voltage constraints do not exceed the 40 V maximum limit during transient conditions.

Part Context

This part belongs to the LT8570 series of PWM DC/DC converters. The series includes variants with different switch currents and frequencies, such as the LT8570 (0.5A switch) and LT8570-1 (0.25A switch). The LT8570HMS8E-1#PBF specifically denotes the H-grade temperature variant in an MSOP-8 package with lead-free termination.
