What are the key features of LT8650SEV#PBF?
- Dual independent synchronous buck channels each rated at 5 A continuous output current
- Wide 3 V to 42 V input range covering automotive 12 V and 24 V bus applications
- Current-mode PWM control for fast transient response and cycle-by-cycle current limiting
- Integrated high-side and low-side power switches eliminating external FETs for BOM savings
- 32-lead compact package enabling dense dual-rail power supply designs on small PCBs
- Adjustable output voltage supporting multiple regulated rails from a single IC
What is LT8650SEV#PBF used for?
LT8650SEV#PBF is designed for automotive ECUs, industrial motor drives, and telecom equipment that need to generate two independent regulated voltage rails from a wide-range input bus. Its dual 5 A channels can power processor cores, FPGAs, DSPs, and peripheral rails simultaneously, reducing the number of discrete power ICs on the board. The 42 V input tolerance and robust current-mode control make it reliable in environments with high-voltage transients, load dumps, and wide temperature excursions common in automotive and industrial deployments.

Frequently Asked Questions
What input voltage range does LT8650SEV#PBF support, and which power bus topologies does it accommodate?
LT8650SEV#PBF accepts input voltages from 3 V to 42 V, covering 5 V USB power, 12 V desktop PC rails, 24 V industrial bus, and automotive battery systems including cold-crank conditions down to 3 V. This wide range makes it versatile for multi-voltage bus architectures where the same regulator IC can serve different system-level power configurations without a redesign.
How does the dual-channel architecture of LT8650SEV#PBF simplify multi-rail power supply design compared to using two separate single-channel buck converters?
By integrating two 5 A synchronous buck channels in a single 32-lead package, LT8650SEV#PBF halves the number of power ICs, reducing PCB area, decoupling component count, and assembly complexity compared to two discrete regulators. Both channels share input filtering, enabling tighter layout and lower common-mode noise on densely populated boards such as automotive ECUs or FPGA carrier cards.
What output current per channel does LT8650SEV#PBF deliver, and is that sufficient for powering an FPGA core and I/O rails simultaneously?
Each channel of LT8650SEV#PBF delivers up to 5 A of continuous output current, which is sufficient to power mid-range FPGA core rails typically drawing 1 A to 3 A and I/O supply rails drawing up to 2 A, all from a single IC. For FPGAs such as Xilinx Spartan-7 or Intel MAX 10 families, the dual 5 A outputs cover both the VCCINT and VCCO domains simultaneously without requiring additional regulators.
