Linear Technology LTC2927 Tracking and Sequencing Circuit Design Note 389
The document introduces the LTC2927 as a versatile solution for managing complex supply voltage tracking or sequencing requirements in multiple-voltage electronics systems. It addresses design difficulties associated with distributed-power architectures where converters are scattered across board space.
Basic operation involves placing a single LTC2927 at the point-of-load to configure supplies to ramp up and down with various profiles using resistors and capacitors. The device allows slave supplies to track a master signal exactly or with different ramp rates, voltage offsets, time delays, or combinations thereof, without altering power supply control loop dynamics.

Questions answered in these manuals
What is the LTC2927 used for?
The LTC2927 provides a solution for tracking and sequencing multiple-voltage electronics systems in point-of-load applications.
From: Linear Technology LTC2927 Tracking and Sequencing Circuit Design Note 389
How does the LTC2927 affect power supply stability?
Power supply stability remains unaffected because the device offsets output voltage without altering control loop dynamics.

What is the supply voltage range of the LTC2927?
The LTC2927 operates with a supply voltage (Voc) from 2.9 V to 5.5 V.
What does the SDO pin do?
The SDO pin is an open‑drain shutdown output that holds the slave supply RUN/SS pin low until the supply voltage exceeds the undervoltage lockout and the ON pin is above its threshold.
