Notes:
3. Percentage of Full Scale (FS) with temperature compensation applied.
4. The device requires a delay period following an enable signal and prior to ramping its output. Precise timing mode limits this
5. Precise ramp timing mode is only valid when using EN pin to enable the device rather than PMBus enable. Precise ramp
6. The devices may require up to a 4 ms delay following the assertion of the enable signal (normal mode) or following the de-
7. Switch node current should not exceed I
8. Factory default is the initial value in firmware. The value can be changed via PMBus commands.
9. Maximum duty cycle is limited by the equation MAX_DUTY(%) = [1 - (150×10
