LT8312HMS#PBF

Overview

The LT8312HMS#PBF is a power factor correction (PFC) boost controller manufactured by Analog Devices Inc. It operates in discontinuous conduction mode (DCM) with a switching frequency of 400 kHz. The device supports a supply voltage range of 10V to 38V and features a startup current of 80 µA. It is housed in a 16-lead MSOP package and is rated for operation between -40°C and +150°C.

Feature Summary

• Active power factor correction achieving factors greater than 0.99
• Current-mode control technique using pulse width modulation
• Designed for discontinuous conduction mode (DCM) applications

Applications

• Power factor correction boost controllers
• Industrial power supplies
• Harsh environment electronic systems

Procurement Notes

Verify the specific suffix #PBF indicates a lead-free, RoHS-compliant tube package variant distinct from tape-and-reel options. Confirm active status and availability through authorized distributors, as supply constraints may apply. Ensure the 16-lead MSOP footprint matches the target PCB design before procurement.

Selection Notes

Select this component for designs requiring high power factor performance in DCM topologies. The wide operating temperature range up to 150°C makes it suitable for industrial environments. Verify that the 400 kHz switching frequency aligns with electromagnetic interference requirements and efficiency targets for the specific application.

Part Context

This part belongs to the LT8312 family of PFC boost controllers from Analog Devices. It shares core functionality with variants like the LT8312IMS#TRPBF but differs in packaging and reel specifications. The series is designed to simplify PFC implementation while maintaining high efficiency and compliance standards.

Replacement Considerations

Direct substitutes include other LT8312 variants such as LT8312IMS#TRPBF, provided the package type (MSOP vs TSSOP) and delivery format are compatible with the assembly process. Cross-reference electrical parameters to ensure compatibility.
