What are the key features of LTC3875IUJ#PBF?
- Dual 2-phase synchronous control with low-value DCR sensing and temperature compensation for accurate current measurement
- Wide 4.5V to 38V input range with output adjustable from 0.6V to 5V enabling versatile multi-rail power supply designs
- Current-mode PWM architecture in a compact QFN package supporting high-efficiency synchronous buck conversion for FPGAs and DSPs
What is LTC3875IUJ#PBF used for?
The LTC3875IUJ#PBF is designed for multi-rail power supplies in high-performance computing, networking equipment, and FPGA-based systems requiring dual synchronized buck outputs. Its 2-phase interleaved operation reduces input capacitor RMS current and output ripple, improving efficiency for loads up to 38V input. Temperature-compensated DCR sensing eliminates power resistors while maintaining accurate current limiting across industrial temperature ranges.

Frequently Asked Questions
What output voltage ranges does LTC3875IUJ#PBF support across its two independent channels?
LTC3875IUJ#PBF provides two independently adjustable outputs, one ranging from 0.6V to 3.5V and the other from 0.6V to 5V, supporting common FPGA core, DDR memory, and I/O power rail voltages from a single controller IC.
How does 2-phase interleaving in LTC3875IUJ#PBF reduce input and output capacitor requirements?
2-phase interleaving in LTC3875IUJ#PBF shifts the two switching phases by 180 degrees, canceling peak input currents and reducing output ripple by up to 50%, allowing smaller capacitors in 4.5V to 38V DC-DC converter designs.
Why is temperature-compensated DCR sensing in LTC3875IUJ#PBF advantageous over sense-resistor-based current monitoring?
Temperature-compensated DCR sensing in LTC3875IUJ#PBF eliminates the power loss of dedicated sense resistors while maintaining accurate current measurement across -40°C to 125°C, reducing BOM cost and improving efficiency in high-current synchronous buck stages.
In which system power architectures is LTC3875IUJ#PBF a better fit than single-phase synchronous controllers?
LTC3875IUJ#PBF is preferred in FPGA, ASIC, and server CPU power stages requiring dual independent rails from 4.5V to 38V bus, where 2-phase operation significantly reduces PCB copper area and filtering compared to two separate single-phase controllers.
