Key Features
- Current-mode PWM control with 1 MHz switching frequency enabling small external inductor and capacitor selection
- Wide 2.5 V to 32 V input range supporting battery, automotive, and industrial supply rails
- Boost and SEPIC topology support in a single controller for flexible output voltage configurations
- 20-pin TSSOP package with spread pins for low-EMI PCB layout in space-constrained designs
- Adjustable soft-start and frequency synchronization for multi-rail power systems with controlled inrush
Applications
The LT8494IFE#PBF is ideal for automotive infotainment and instrument-cluster boards requiring a stable regulated output from a 12 V battery that may dip as low as 2.5 V during cold-crank conditions. Its 1 MHz switching frequency minimizes filter component size, making it attractive for portable industrial test instruments and handheld medical devices powered from Li-Ion cells. SEPIC topology support also allows it to produce an output voltage either above or below the input, simplifying power-path design in battery-backup and multi-chemistry charging systems.

Frequently Asked Questions
What input voltage range does the LT8494IFE#PBF support for automotive and industrial designs?
The LT8494IFE#PBF accepts input voltages from 2.5 V to 32 V, covering standard 12 V automotive batteries through cold-crank drop-outs as well as 24 V industrial rails, making it versatile for systems that must operate continuously across a wide supply variation.
How does the 1 MHz switching frequency of the LT8494IFE#PBF benefit PCB size?
Operating at 1 MHz allows engineers to use inductors as small as 4.7 µH and ceramic output capacitors in the 10 µF to 22 µF range, shrinking the total power stage footprint compared to a 300 kHz design and making the TSSOP-20 IC well-suited for compact boards.
When should a designer choose a SEPIC topology over a simple boost with the LT8494IFE#PBF?
SEPIC mode is the better choice when the output voltage must be both above and below the input, for example in a 5 V output system powered from a 3.6 V Li-Ion cell that rises to 4.2 V fully charged; the SEPIC maintains regulated 5 V output across the full 2.5 V to 32 V input range without a switch that shorts input to output.
What package does the LT8494IFE#PBF use and how many pins does it have?
The LT8494IFE#PBF is packaged in a 20-pin TSSOP (Thin-Shrink Small Outline Package) with a 0.65 mm pitch, offering a compact 6.5 mm x 4.4 mm footprint that fits dense multilayer PCBs used in automotive and portable industrial equipment.
