LT8312MPMS#TRPBF

Overview

The LT8312MPMS#TRPBF is a power factor correction (PFC) boost controller manufactured by Analog Devices Inc. It operates at a switching frequency of 400 kHz and is housed in a 16-lead MSOP package. The device supports discontinuous conduction mode (DCM) operation to achieve a power factor greater than 0.99. It functions within a minimum operating temperature of -40°C and a maximum operating temperature of +125°C.

Feature Summary

• Active power factor correction modulation achieving factors exceeding 0.99
• Discontinuous conduction mode (DCM) control architecture
• Integrated 400 kHz fixed switching frequency

Applications

• Power factor correction boost controllers
• High-efficiency AC/DC power supplies
• Industrial power conversion systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the MP grade designation for military-grade temperature specifications against the official datasheet. Ensure compatibility with 16-lead MSOP footprints during procurement planning.

Selection Notes

Select this component for designs requiring high power factor performance in DCM applications. Verify that the 400 kHz switching frequency aligns with system EMI requirements. Ensure the MSOP-16 package fits the available PCB real estate and thermal management strategy.

Part Context

This part belongs to the LT8312 series of PFC boost controllers from Analog Devices. It shares core functionality with other variants in the family but is distinguished by its specific military-grade temperature range and commercial packaging configuration.

Replacement Considerations

LT8312MPMS#PBF is a tube-packaged alternative with identical electrical characteristics. Verify package handling differences if transitioning between reel and tube formats.
