Overview
The LT8292AFE#WTRPBF is a synchronous buck-boost DC-DC controller from Analog Devices Inc., designed for automotive applications with AEC-Q100 qualification. It operates within an input voltage range of 5.5V to 60V and supports switching frequencies between 100kHz and 650kHz. The device features low quiescent current, clock synchronization, and integrated soft-start capabilities. Packaged in a 38-TSSOP-EP (TFSOP) with exposed pad, it functions as a positive output step-up/step-down regulator suitable for wide input voltage ranges.
Feature Summary
- Synchronous buck-boost topology supporting both step-up and step-down conversion modes
- AEC-Q100 qualified for automotive grade reliability and thermal performance
- Integrated iShare capability for parallel operation and load sharing
- Supports spread spectrum frequency modulation to reduce EMI
Applications
- Automotive infotainment systems requiring wide input voltage tolerance
- Battery-powered industrial equipment with varying supply levels
- Telecommunications base stations utilizing bus voltage regulation
- General purpose DC-DC conversion in harsh environmental conditions
Procurement Notes
Verify the specific suffix WTRPBF indicates tape and reel packaging when ordering. Confirm that the AEC-Q100 qualification aligns with your system's automotive reliability requirements. Ensure the 38-TSSOP-EP footprint matches your PCB layout constraints. Cross-reference the datasheet for thermal pad soldering recommendations to maintain optimal heat dissipation during high-load operations.
Selection Notes
Select this component when a wide input voltage range up to 60V is required alongside buck-boost functionality. Consider its low IQ feature for battery efficiency in standby modes. Evaluate the 38-pin package size against available board space. Check compatibility with external components for the desired switching frequency range between 100kHz and 650kHz.
Part Context
This part belongs to the LT8292 family of synchronous buck-boost controllers. It shares core architecture with variants like LT8292AFE#WPBF but differs in packaging format. The series targets high-efficiency power management in automotive and industrial sectors. It complements other Analog Devices PMIC solutions by providing flexible topology options for complex power rails.
Replacement Considerations
LT8292AFE#WPBF serves as a direct functional equivalent differing only in tube versus tape-and-reel packaging. Verify pinout compatibility before substitution. Ensure thermal characteristics remain consistent across packaging types. No alternative part numbers are publicly confirmed as direct substitutes.
