... EN5364QI-EN5394QI Evaluation Board Application Note voltage may be coupled to the output via a diode. This diode (D2) is populated on the board. Back-feed voltage may be applied at BF_IN (TP18) Parallel Mode operation o operated in parallel when load currents greater than 6A/9A is desired. In parallel mode, one device is designated the Master and devices operate in slave mode, controlled by the Master ...

... EN5364QI-EN5394QI Evaluation Board Application Note • The phase delay is set by connecting a resistor from S_delay to AGND. The delay is approximately: Delay (nsec) = 2*[S_delay resistance in kΩ.] A 49.9kΩ (populated on Evaluation board) resistor value delays the clock signal by ~100nsec. • EN53x4QI supports pre-bias mode operation. To use this option set the EN_PB jumper to pre-bias enable position with device powered down ...
