Overview
The LT8228HFE#TRPBF is a bidirectional synchronous buck/boost controller from Analog Devices, designed for high-voltage applications up to 100V. It supports constant-current or constant-voltage modes with independent compensation networks. The device operates within a switching frequency range of 80kHz to 600kHz and features synchronous rectification. It is housed in a 38-lead TSSOP-EP package and functions across an operating temperature range of -40°C to 150°C TJ.
Feature Summary
- Bidirectional synchronous buck and boost control capability
- Independent compensation network for flexible loop stability
- Integrated reverse supply and reverse current protection
Applications
- High-voltage battery management systems
- Industrial power supplies requiring bidirectional energy flow
- Automotive electronics with 100V bus architectures
Procurement Notes
Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm that the HFE variant matches the required thermal pad configuration for your PCB layout. Ensure compatibility with the 100V maximum input/output voltage ratings for your system design. Check for any recent product change notifications regarding pinout or electrical characteristics updates.
Selection Notes
Select this component for designs requiring robust bidirectional power conversion in high-voltage environments. The independent compensation network allows optimization for both buck and boost modes without retuning. Consider the 38-lead TSSOP-EP package for adequate thermal dissipation. Verify that the 80kHz to 600kHz frequency range aligns with your electromagnetic interference constraints.
Part Context
The LT8228 series includes variants such as LT8228IFE and LT8228HFE, differentiated by package type and thermal performance. This controller belongs to Analog Devices' PMIC portfolio focused on high-voltage power management. It complements other buck/boost controllers by offering specialized protection features for sensitive loads.
Replacement Considerations
LT8228IFE#TRPBF serves as a direct functional substitute within the same family, sharing identical electrical specifications and control logic. Both parts are bidirectional synchronous controllers with 100V ratings. Verify package compatibility if transitioning between different leaded options.
