Enpirion Power Evaluation Board User Guide EN5339QI PowerSoc EN5339QI 3A Synchronous DCDC Converter Evaluation Board User Guide Introduction Thank you for choosing Altera Enpirion power products You are evaluating Altera Enpirions EN5339QI low profile 3A PowerSoC. The device is a fully integrated step down DCDC converter with control/compensation, gate drive, MOSFET switches and Altera Enpirions proprietary high performance magnetics. It comes in a 4mm x 6mm x 1.1mm low profile package and requires only a small number of external components to make a complete converter solution This user guide should be used together with the latest device datasheet. The datasheet can be found at www.altera.com/enpirion. Following are the features of this evaluation board. Populated with one EN5339QI 3A 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 or 0805 case size while the other three positions can accommodate either 0805 or 0603 capacitor case sizes. The base output capacitor configuration is 3 x 22uF 0805 MLCC. Refer to the product datasheet for output capacitor requirements. There are two positions for the input capacitors which can accommodate either 0805 or 0603 case sizes. 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: 1.0V, 1.2V, 1.5V, 1.8V Easy jumpers are provided for the following signals: Enable 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. 1 www.altera.com/enpirion Enpirion Power Evaluation Board User Guide EN5339QI PowerSoc Quick Start Guide Figure 1 shows a photograph of the evaluation board. Please refer to this figure while configuring the board for evaluation. STEP 1: Set the ENABLE jumper to the Disable Position. ENABLE DISABLE STEP 2: Select the desired VOUT voltage setting by placing the jumper J2 on the correct jumper pin. Below shows the VOUT jumper options. CAUTION: the VOUT jumper settings can only be changed when the device is disabled. Failure to follow this guideline may result in damage to the part. STEP 3: Connect the Power Supply to the input power connectors, VIN (+) and GND (-). DO NOT turn the power supply on yet. CAUTION: be mindful of the polarity. Reversing polarity will result in damage to the part. STEP 4: Connect an electronic load, or load board to the load to the output connectors VOUT (+) and GND (-). STEP 5: Power up the board and move the ENABLE jumper to the enabled position. The EN5339QI is now powered up. 2 www.altera.com/enpirion
