Overview
The LT8312EMS#TRPBF is a power factor correction (PFC) boost controller manufactured by Analog Devices Inc. It operates in Discontinuous Conduction Mode (DCM) with a fixed switching frequency of 400kHz. The device supports a supply voltage range of 10V to 38V and features a low startup current of 80 µA. Packaged in a 16-lead MSOP, this active component is designed for high-efficiency power conversion applications requiring precise control.
Feature Summary
- Actively modulates input current to achieve a power factor greater than 0.99
- Operates in Discontinuous Conduction Mode (DCM) for efficient light-load performance
- Integrated boost controller architecture simplifies PFC circuit design
Applications
- Power factor correction circuits in AC-DC converters
- High-efficiency power supplies requiring PF > 0.99
- Industrial power management systems
Procurement Notes
Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the 16-lead MSOP package type matches your PCB footprint requirements. Ensure the 10V to 38V supply voltage range aligns with your system's operational limits. Cross-reference the DCM mode specification with your load profile needs.
Selection Notes
Select this component for designs requiring a dedicated PFC boost controller with DCM operation. The 400kHz switching frequency offers a balance between size and efficiency. Consider the 80 µA startup current for low-power standby applications. Verify compatibility with external MOSFETs and inductors for the target power level.
Part Context
This part belongs to the LT8312 family of power factor correction controllers from Analog Devices. It is specifically engineered for boost converter topologies where high power factor compliance is mandatory. The EMS variant denotes the commercial temperature grade and MSOP package style within the broader product line.
Replacement Considerations
LT8312HMS#PBF is a documented substitute offering similar functionality in a tube package. Verify pinout compatibility and thermal characteristics before substitution. Ensure the replacement meets the same 400kHz frequency and DCM mode specifications.
