Overview
The LT3511HMS#PBF is a micropower isolated flyback converter manufactured by Analog Devices Inc. It integrates a high-voltage switch rated for 150V and 260mA, eliminating the need for external startup resistors. The device operates from an input voltage range of 4.5V to 100V and supports adjustable switching frequencies up to 200kHz. Packaged in a thermally enhanced MSOP-10, it includes internal soft-start and cycle-by-cycle current limiting for robust operation in space-constrained applications.
Feature Summary
- Integrates a 150V/260mA power switch with no requirement for external startup resistors
- Supports wide input voltage ranges suitable for various industrial supply standards
- Includes internal soft-start functionality to limit inrush current during initialization
Applications
- Isolated DC-DC conversion for industrial control systems
- Power supplies for instrumentation and measurement equipment
- Telecommunications interface circuits requiring galvanic isolation
Procurement Notes
Verify the specific suffix and package variant against the official datasheet to ensure compatibility with thermal requirements. Confirm availability status as distribution channels may report limited stock or end-of-life conditions. Cross-reference the manufacturer's latest documentation for any design-in updates or recommended alternative components prior to finalizing procurement orders.
Selection Notes
Select this component when designing isolated flyback converters that require minimal external component count and high input voltage tolerance. Evaluate the thermal performance of the MSOP-10 package against the expected power dissipation levels. Ensure the selected switching frequency aligns with transformer design constraints and electromagnetic interference requirements for the target application environment.
Part Context
This part belongs to the LT3511 family of micropower isolated flyback converters designed by Analog Devices. These devices are engineered to simplify the design of isolated power stages by integrating high-voltage switching capabilities directly into the IC. The family targets applications where board space is limited and efficiency at light loads is critical for overall system performance.
Replacement Considerations
Consult official substitution guides for equivalent isolated flyback controllers. Verify pinout compatibility and electrical specifications before replacing existing designs.
