Introduction
Thank you for choosing Enpirion, the source for ultra small foot print power converter
products that offer true ease of design with no compromise on performance. This
evaluation board user guide applies to the EN5329 devices mounted on PCB’s with the
part number 08251 rev A on the backside. This user guide should be used together with
the latest device datasheet. The datasheet can be found at www.enpirion.com.
Following are the features of this evaluation board.
Enpirion 2013 all rights reserved, E&OE
EN5329QI 2A Synchronous DC/DC Converter
Populated with one EN5329QI 2A PowerSoC with integrated inductor.
Pre-tinned pads are available for a wide range of input and output capacitor
configurations.
There are four positions available for the output capacitors. The first position,
closest to the IC, can accommodate a 1206, 0805, or 0603 case size while the
other three positions can accommodate either 0805 or 0603 capacitor case
sizes.
The base output capacitor configuration is 2 x 22uF 0603 MLCC. Refer to the
product datasheet for output capacitor requirements.
There are two positions for the input capacitors. The first position, closest to the
IC, can accommodate an 0805 or 0603 case size while the other position can
accommodate an 0805 case size. The base input capacitor configuration is a
single 22uF 0805 MLCC. Refer to the product datasheet for input capacitor
requirements.
Output voltage programming is accomplished via a simple resistor divider.
Jumpers are provided for 4 pre-configured output settings. These settings are as
follows:
Easy jumpers are provided for the following signals:
Numerous test points are provided as well as clip leads for input and output
connections
The board comes with input decoupling and reverse polarity protection.
