Overview
The LT8301ES5#TRPBF is a micro-power isolated flyback converter featuring an integrated 65V/1.2A switch, designed for applications requiring no optocoupler feedback. It operates with an input voltage range up to 42V and delivers a regulated output of 65V at 1.2A. The device utilizes a TSOT-23-5 surface-mount package and supports a switching frequency of 10.6kHz. Quiescent current is specified at 350µA, with a minimum operating temperature rating of -40°C.
Feature Summary
- Integrated high-voltage power switch eliminates external component count
- Optocoupler-less regulation simplifies transformer design and isolation barrier
- Compact TSOT-23-5 package suitable for space-constrained designs
Applications
- Isolated DC-DC conversion for industrial sensors
- Medical equipment power supplies
- Automotive electronics requiring galvanic isolation
Procurement Notes
Verify availability status directly with Analog Devices or authorized distributors, as supply constraints may apply. Confirm RoHS compliance and lead times prior to order placement. Ensure the specific suffix matches required packaging and temperature grades. Cross-reference datasheet revisions to confirm parameter consistency.
Selection Notes
Select this component when a compact, isolated flyback solution is needed without optocouplers. Evaluate thermal performance within the TSOT-23-5 package limits. Consider the 42V maximum input constraint against system requirements. Verify that the 65V switch rating accommodates peak voltages including reflected output voltage and spikes.
Part Context
Part of the LT8301 family of micro-power isolated flyback converters. Shares architectural similarities with LT8300 and LT8302 series but differs in switch voltage/current ratings and package options. Designed for low-power isolated applications where size and simplicity are critical.
Replacement Considerations
LT8300ES5#PBF offers similar functionality with different output specifications. LT8302 provides higher current capability in an SOIC-8 package. Verify pinout compatibility and electrical parameters before substitution.
