This manual introduces the EVAL-LT8692S-AZ evaluation board, a 4-rail power supply featuring one LT8692S 42V/2A synchronous step-down regulator and three LT8692S 8V/1A synchronous step-down regulators. The four regulators are synchronized to a 2MHz clock and can provide 5V, 3.3V, 1.8V, and 1.2V outputs.
This document is a demonstration manual for the EVAL-LT8692S-AZ circuit board. The board utilizes the LT8692S, a 42V quad monolithic synchronous step-down Silent Switcher regulator, to generate four independent output voltages: 5V, 3.3V, 1.8V, and 1.2V from a nominal 12V input. The 5V channel provides 2A of current, while the other three channels provide 1A each.
| Input Voltage | 6.2V to 42V |
|---|---|
| Channel 1 Output Voltage | 5V |
| Channel 2 Output Voltage | 3.3V |
| Channel 3 Output Voltage | 1.8V |
| Channel 4 Output Voltage | 1.2V |
| Channel 1 Max Current | 2A |
| Channel 2-4 Max Current | 1A |
| Switching Frequency | 2MHz |
The default outputs are 5V, 3.3V, 1.8V, and 1.2V.
The input voltage range is from 6.2V to 42V.
The LT8692S is a quad regulator with four output channels.
