What are the key features of LT8494EUF#PBF?
- Current-mode PWM boost/SEPIC topology operating at 1 MHz switching frequency enables compact inductor and capacitor selection
- Wide 2.5 V to 32 V input voltage range covers automotive battery (12 V nominal) and industrial supply rails in a single design
- 20-pin QFN package (5 mm x 5 mm) provides a small thermal footprint with exposed pad for efficient heat dissipation in high-power density applications
What is LT8494EUF#PBF used for?
The LT8494EUF#PBF is well suited for automotive infotainment systems, industrial sensors, and portable instrumentation where a stable output rail must be maintained across a wide 2.5 V to 32 V input range. Its 1 MHz switching frequency minimizes external component size, and the boost/SEPIC topology allows the output voltage to be set above, below, or equal to the input, making it ideal for battery-powered designs where input voltage spans the regulation point during charge and discharge cycles.

Frequently Asked Questions
What input voltage range and switching frequency does the LT8494EUF#PBF support for boost and SEPIC designs?
The LT8494EUF#PBF accepts input voltages from 2.5 V to 32 V and switches at 1 MHz. This combination allows the use of compact 1 µH to 4.7 µH inductors and small ceramic output capacitors, substantially reducing total solution size compared to 300 kHz alternatives while maintaining high conversion efficiency across the full input range.
In which automotive or industrial power conversion scenarios does the LT8494EUF#PBF's SEPIC topology offer an advantage?
SEPIC topology lets the LT8494EUF#PBF regulate an output voltage that is higher, lower, or equal to the input — a critical capability in automotive 12 V systems where the battery voltage spans 9 V to 16 V and a fixed 12 V or 15 V output rail must be maintained throughout. This avoids the need for separate boost and buck converters, saving board space and BOM cost in automotive ECUs and industrial sensors.
How does the 20-pin QFN package of the LT8494EUF#PBF assist thermal management in high-power density applications?
The 20-pin QFN package includes an exposed bottom thermal pad that conducts heat directly into the PCB copper ground plane, reducing junction-to-board thermal resistance to approximately 20°C/W. At 1 MHz and up to 32 V input, this package allows the LT8494EUF#PBF to deliver multi-watt output power without a heatsink in ambient temperatures up to 85°C, provided adequate copper pour is used beneath the IC.
