What is the delay time of DVS (including the delay after I2C command + Vout ramp up time)?
The MAX77654 does support programmable output voltage through I2C, though the slew rate is not fixed.
- Delay from I2C command to voltage change can range from 12ms to 64ms.
- Output voltage slew rate:
- Rising = dependent on inductor current peak limit, output voltage change, and output capacitor.
- Example with 1A IPEAK, 22uF cap. and changing output voltage by +0.1V:
- Rising = 0.0294 V/us
- Example with 1A IPEAK, 22uF cap. and changing output voltage by +1.5V:
- Rising = 0.0227 V/us
- Example with 1A IPEAK, 22uF cap. and changing output voltage by +0.1V:
- Falling = depends on load
- Rising = dependent on inductor current peak limit, output voltage change, and output capacitor.
