Product details

What this dual-output VID controller does

The LTC3877EUK#PBF is a dual-output, 6-bit VID step-down DC/DC controller from Analog Devices (Linear Technology heritage) designed for point-of-load regulation in server, telecom, and industrial systems. It accepts a 4.5V to 38V input rail and delivers two independent regulated outputs — one adjustable from 0.6V to 3.5V, the other from 0.6V to 5V — controlled via a 6-bit VID code for dynamic voltage scaling.

ROHS3 compliant. No official second source or pin-compatible replacement is recorded; for dual-sourcing resilience, evaluate the LTC3877 family's other VID-code variants or a discrete controller pair.

Frequently asked questions

What output voltages can LTC3877EUK#PBF generate?

It provides two independent regulated outputs: one adjustable from 0.6V to 3.5V (typical for a CPU core or ASIC rail) and the other from 0.6V to 5V (typical for I/O or memory voltage). Both are set via a 6-bit VID code.
