What are the key features of LT8631EFE?
- Dual independent 1.5 A synchronous step-down channels supply two regulated rails from a single 2.7 V to 17 V input
- Adjustable switching frequency up to 2.25 MHz minimizes external inductor and capacitor sizes for compact power stage layouts
- Integrated power MOSFETs in a compact 16-pin TSSOP package simplify design and reduce total solution footprint
- Burst Mode operation minimizes quiescent current for high efficiency at light loads in battery-powered and portable systems
What is LT8631EFE used for?
The LT8631EFE is well suited for multi-rail power supply designs in telecommunications equipment, industrial instrumentation, and embedded computing systems that require two independently regulated outputs from a single converter IC. Its 2.7 V to 17 V input range supports both battery-powered applications and regulation from 12 V or 15 V system bus rails. High switching frequency operation reduces external inductor and capacitor sizes for ultra-compact PCB power stages.

Frequently Asked Questions
What input voltage range and output current does the LT8631EFE dual buck regulator support?
The LT8631EFE accepts input voltages from 2.7 V to 17 V and provides two independently regulated step-down outputs, each delivering up to 1.5 A of continuous current, making it ideal for dual-rail power architectures in industrial, communications, and embedded computing applications requiring compact multi-output regulators.
How does the LT8631EFE's high switching frequency reduce external component sizes in a power supply design?
The LT8631EFE supports switching frequencies up to 2.25 MHz, enabling use of small inductors and ceramic capacitors that shrink overall PCB footprint. With 1.5 A per channel output capability and frequency synchronization support, it also minimizes EMI interference on noise-sensitive analog and RF circuits sharing the same board.
When does using the LT8631EFE outperform deploying two separate single-channel buck regulators?
The LT8631EFE integrates two 1.5 A synchronous step-down channels in a single 16-pin TSSOP, eliminating duplicate gate drivers and halving the IC count compared to two single-channel regulators. This reduces bill-of-materials cost and PCB area in multi-rail systems powering DSP cores, FPGAs, and peripheral buses from a common 5 V or 12 V input rail.
