Evaluation Board for the ADP5051/ADP5053 4-Channel Power Management Unit PMU with Supervisory

Wide input voltage range V to 15 V Full featured evaluation board for the ADP5051/ADP5053 CH1 programmable A/2.5 A/4 A buck regulator CH2 programmable A/2.5 A/4 A buck regulator CH3 A sync buck regulator CH4 A sync buck regulator Standalone operation capability USB dongle and GUI software support ADP5051 only Dedicated enable option for each channel Mode option to select PSM or FPWM operation Programmable switching frequency from 250 kHz to MHz Frequency synchronization input or output Simple device measurements and demonstrable with Voltage supply Voltmeter Ammeter Load resistors or electrical load Open-drain processor reset with external adjustable threshold monitoring Manual reset input

Hardware Requirement

USB-to-I2C dongle USB-SDP-CABLEZ The USB-SDP-CABLEZ is not included in the evaluation kit and must be ordered separately. Only one dongle is required in a multiboard cascade setup

Software Requirement

ADP505x DEMO GUI software

This user guide describes the hardware and software for the evaluation of the ADP5051/ADP5053, including detailed schematics and printed circuit board PCB layouts. The ADP5051/ADP5053 evaluation board combines four high performance buck regulators and supervisory in a 48-lead LFCSP package to meet demanding performance and board space requirements. The ADP5051/ADP5053 evaluation board can connect to high input voltages, up to 15 V directly, without any preregulators. The ADP5051/ADP5053 share a common PCB evaluation board however, whereas the ADP5051 board can support an external USB dongle connection and GUI software to evaluate the comprehensive functionalities provided by an I2C interface, the ADP5053 has no I2C interface capability. Both the ADP5051 and the ADP5053 operate in the same manner and are available in an adjustable voltage option. Full details on the devices are provided in the ADP5051/ADP5053 data sheet available from Analog Devices, Inc., and should be consulted in conjunction with this evaluation board user guide.

INSTALLING THE SOFTWARE ADP5051 ONLY

Note that the ADP5051 evaluation board can be powered up in standalone operation without the GUI software. Using the GUI software to access the advanced functionality of the ADP5051 product is optional. Before starting the software installation, ensure that the ADP5051 evaluation board is not connected to the USB port of the PC.

INSTALLING LABVIEW

Note that if the PC has LabVIEW already installed, this following step is not needed. The application software is a compiled LabVIEW program, which requires LabVIEW or later and a
run-time engine installed on the PC. You can download the LabVIEW run-time engine on the National Instrument website. A LabVIEW run-time installation is available on the ADP5051 installation CD.

INSTALLING THE ADP5051 GUI SOFTWARE

After installation, it may be necessary to reboot the PC to complete the operation. Launch the Setup.exe file. When the dialog box shown in Figure 2 appears, click Next to continue.

INSTALLING THE ANALOG DEVICES SDP DRIVERS ADP5051 ONLY

To install the Analog Devices SDP Drivers, complete the following steps After installing ADP505x Demo GUI software properly, the installation of the Analog Devices SDP drivers begins. Click Next to install the drivers see Figure

Figure ADI SDP Drivers Setup Wizard Click Install after verifying the program folder. Ensure that the system environment has enough space see Figure

Figure Verify the Destination Folder Click Finish to complete the driver installation see Figure

Figure Driver Installation Complete To verify that the USB driver is installed properly, click Start. Then select Control Panel > System and open the Device Manager see Figure

When the USB dongle is connected to a PC port different from the one used to install the driver, the PC device driver may ask you to install the driver again for that specific port. If this happens, repeat the first four steps listed in this section.

USING THE EVALUATION BOARD

POWERING UP THE EVALUATION BOARD

The ADP5051/ADP5053 evaluation board is supplied fully assembled and tested. Before applying power to the evaluation board, follow the procedures in this section.

Enable Jumpers

Each channel has its own enable pin, which must be pulled high to enable that channel see Table To disable the channel, pull the enable pin low or leave it floating.

The enable control for each regulator has a V precision enable threshold, which allows the ADP5051/ADP5053 to be easily sequenced between channels or other input/output supplies. It can also be used as a programmable UVLO input by the resistor divider.

When the external hardware enable pin is high, the CHx_ON enable register setting in the ADP5051 GUI software can be used to power down each channel operation.
