Overview
The LT3511MPMS#TRPBF is a high-voltage monolithic switching regulator designed for isolated flyback topologies. It operates with an input voltage range of 4.5V to 100V and provides a maximum output current of 240mA. The device integrates a 100V switch and eliminates the need for third windings or opto-isolators. Key electrical parameters include a quiescent current of 2.7 mA and a fixed switching frequency of 650 kHz. It functions within a minimum operating temperature of -55°C.
Feature Summary
- Designed specifically for isolated flyback converter applications
- Integrates a high-voltage 100V internal switch
- Eliminates requirement for auxiliary windings or opto-isolators
- Supports wide input voltage ranges up to 100V
Applications
- Isolated power supplies
- High-voltage DC-DC conversion
- Industrial control systems requiring galvanic isolation
Procurement Notes
Verify the exact suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm Analog Devices Inc. as the manufacturer. Ensure RoHS compliance status matches project requirements. Cross-reference the MSOP-12 package dimensions against PCB layout constraints. Validate the specific lot date code if traceability is required for critical infrastructure.
Selection Notes
Select this component when designing isolated flyback converters requiring high input voltages without external opto-isolators. The integrated 100V switch simplifies design compared to discrete solutions. Consider the 650 kHz switching frequency for size optimization. Verify thermal performance in the MSOP-12 package for the intended load conditions.
Part Context
This part belongs to the LT3511 series from Analog Devices, which focuses on high-voltage switching regulators. The MPMS variant denotes the specific MSOP-12 package type. The series is engineered to simplify isolated power supply designs by removing complex feedback components typically needed in flyback architectures.
Replacement Considerations
LT3511EMS#TRPBF and LT3511HMS#TRPBF are documented variants within the same family. These share core functional specifications but may differ in temperature grades or package availability. Verify pin compatibility and thermal characteristics before substitution.
