LTC2927 is a single power supply tracking controller from LTC company, which can achieve VCORE and VI/O power tracking, suitable for microprocessor, DSP and FPGA power supplies, supporting multiple power supply systems, power tracking, power sequencing and other functions.
The LTC2927 is a power‑supply tracking and sequencing controller that can be configured to ramp‑up and ramp‑down supplies with independent rates, voltage offsets, or delays. It tracks a master signal by mirroring current from the TRACK pin to the FB pin, allowing precise control of slave supplies without affecting stability.
The document includes electrical characteristics, pin configurations for DFN and TSOT‑23 packages, functional block diagrams, and typical application circuits. It also provides design guidance, package dimensions, and a list of related Linear Technology products.
| Supply Voltage (Voc) | 2.9 V – 5.5 V |
|---|---|
| ON Pin Threshold Voltage (typical) | 1.23 V |
The LTC2927 operates with a supply voltage (Voc) from 2.9 V to 5.5 V.
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.
