Overview
The LT3001ES5#TRMPBF is a micropower isolated flyback converter manufactured by Analog Devices Inc. It operates with an input voltage range up to 36V and delivers a fixed output of 4W without requiring an optocoupler for feedback isolation. The device integrates a high-voltage switch and control logic into a compact TSOT-23-5 surface-mount package. Designed for applications requiring galvanic isolation, it supports a wide operating temperature range from -40°C to +125°C. Key electrical characteristics include a quiescent current of 18µA and a switching frequency of 100kHz, enabling efficient power conversion in space-constrained designs.
Feature Summary
- Eliminates the need for optocouplers through proprietary no-opto isolated flyback architecture
- Integrates high-voltage switch and controller within a minimal footprint package
- Provides stable regulated output across wide input voltage variations
- Supports operation in extreme industrial temperature environments
Applications
- Industrial sensor isolation interfaces
- Medical equipment signal conditioning circuits
- Telecommunications interface protection
- Battery-powered instrumentation systems
Procurement Notes
Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm datasheet revision matches production batch requirements. Ensure storage conditions comply with moisture sensitivity level specifications. Validate pinout compatibility during PCB layout integration. Request material declaration documentation for regulatory compliance verification prior to procurement finalization.
Selection Notes
Evaluate thermal performance constraints relative to enclosure design and ambient conditions. Assess input voltage stability against source impedance variations. Consider load transient response requirements for downstream circuitry. Compare efficiency metrics against alternative non-isolated solutions where applicable. Verify regulatory compliance standards relevant to end-product certification processes.
Part Context
This component belongs to the LT3001 family of micropower isolated converters. It shares architectural similarities with the LT3002 but differs in power output ratings and specific packaging configurations. The ES5 suffix indicates the TSOT-23-5 package variant optimized for space-constrained applications. The TRMPBF designation specifies tape-and-reel packaging with lead-free finish compliant with RoHS directives.
Replacement Considerations
LT3002ES5#TRMPBF offers higher power capacity within identical packaging. LT8301ES5#TRPBF provides extended input voltage ranges up to 42V. LT3001ES8#TRMPBF utilizes an SOT-23-8 package for improved thermal dissipation.
