Introduction

Thank you for choosing Enpirion, the source for ultra small foot print power converter

products! This evaluation board user guide applies to EN5367QI. The EN5367QI is a 6A

device. In addition to this document, you will also need the latest device datasheet.

level of integration delivers a substantial reduction in footprint and parts count

over competing solutions. The evaluation board is optimized for engineering ease

of testing through programming options, clip leads, test points etc.

and has a phase lead capacitor in parallel. One of 4 lower resistors is selected

with the jumper option for different output voltages to change V

upper resistor and capacitor values and change only the lower resistor.

board, we strongly recommend the customer to ensure the feedback loop is truly

closed before powering up the device especially if the load can not withstand the

input voltage.

available to have multiple input and output capacitors. This allows for evaluation

of performance over a wide range of input/output capacitor combinations.
