Frequently Asked Questions

How many output channels does the LTM4644EY-1#PBF provide, and what is the maximum current per channel?

The LTM4644EY-1#PBF integrates 4 independent step-down output channels, each rated at 4 A, giving a total of 16 A when all channels are paralleled. Outputs are adjustable from 0.6 V to 5.5 V, making the device flexible for multi-rail FPGA and ASIC power designs.

What input voltage range does the LTM4644EY-1#PBF support, and is it compatible with a standard 12 V bus?

The LTM4644EY-1#PBF operates from a 4 V minimum to 14 V maximum input, so it is fully compatible with the standard 12 V intermediate bus found in servers and networking equipment. The nominal 12 V input is within the rated range, and the device maintains regulation down to 4 V for lower-voltage rail inputs.

Which FPGA families benefit most from using the LTM4644EY-1#PBF as a power solution?

Xilinx UltraScale, Intel Stratix 10, and similar high-density FPGAs that require multiple supply rails at 0.8 V, 1.0 V, 1.8 V, and 3.3 V are prime candidates. The 4-channel architecture with 4 A per rail covers core, auxiliary, and I/O voltage domains from a single 12 V supply without external inductors.

What control topology does the LTM4644EY-1#PBF use, and how does it affect transient response?

The device uses current-mode pulse-width modulation (PWM) control, which provides inherent cycle-by-cycle current limiting and faster transient response than voltage-mode designs. This topology allows output voltage deviations to be corrected within a few hundred nanoseconds, supporting tight tolerance rails for sensitive digital loads at switching frequencies up to 1 MHz.
