• The phase delay is set by connecting a resistor from S_delay to AGND.
• EN53x4QI supports pre-bias mode operation. To use this option set the
• Jumpers are provided for ease of logical high/low programming of the

The delay is approximately:
A 49.9kΩ (populated on Evaluation board) resistor value delays the clock
signal by ~100nsec.
EN_PB jumper to pre-bias enable position with device powered down.
When the device is subsequently powered and enabled, the output
voltage will ramp monotonically from its pre-bias value to the programmed
value. Pre-bias voltage may be applied to clip lead BF_IN on the
evaluation board. A diode D2 is populated on the board between BF_IN
and VOUT.
following signals:
Enable may also be controlled using an external switching source by
removing the jumper and applying the enable signal to the middle pin and
ground.
