LT8301MPS5#TRMPBF

Overview

The LT8301MPS5#TRMPBF is a micropower isolated flyback converter from Analog Devices. It features an input voltage range of 2.7V to 42V and integrates a 65V, 1.2A DMOS power switch. The device operates with a quiescent current of 350µA in active mode and 100µA in sleep mode. It utilizes boundary mode operation at heavy loads and low-ripple Burst Mode operation at light loads. The component is housed in a 5-lead TSOT-23 package and supports output voltage programming via a single external resistor without requiring a third transformer winding or opto-isolator.

Feature Summary

Eliminates the need for opto-isolators and third transformer windings by sampling the isolated output voltage directly from the primary-side flyback waveform.
Integrates a 65V, 1.2A DMOS power switch along with high-voltage circuitry and control logic into a compact 5-lead TSOT-23 package.
Maintains high efficiency at light loads through low-ripple Burst Mode operation while minimizing output voltage ripple.

Applications

Isolated auxiliary and housekeeping power supplies
Automotive power supply systems
Industrial power supply designs

Procurement Notes

Verify the specific suffix MPS5 against official Analog Devices documentation to confirm temperature grade and packaging specifications. Ensure compatibility with AEC-Q100 automotive qualification requirements if applicable to the target design. Cross-reference datasheet electrical characteristics to validate performance under intended operating conditions.

Selection Notes

Select this component for applications requiring isolation without opto-isolators to reduce component count and size. Suitable for designs needing a wide input voltage range up to 42V. Ideal for space-constrained environments due to the small TSOT-23 footprint. Consider thermal management requirements associated with the integrated 1.2A switch capability.

Part Context

This part belongs to the LT8301 family of micropower isolated flyback converters. The series is characterized by primary-side regulation capabilities and integration of high-voltage switches. Variants within the family typically differ in temperature ranges, package types, and switching frequency options while maintaining core regulation architectures.
