Would You Be Interested in Roadtesting a Current Mode Control DC/DC converter with Fast Transient Response?

I will be roadtesting this product in September. I'd like to get your feeedback, thoughts and interest in this product.

Here are a few facts about the product:

The BD9G500EFJ-EVK-001 uses BD9G500EFJ-LA to output 5V from a 48V input voltage. The input voltage of the BD9G500EFJ-LA is from 7V to 76V and the output voltage is configurable from 1V to 0.97 x VIN V with external resistors. The operating frequency is configurable between 100 kHz and 650 kHz with an external resistor connected to RT pin. This is a current mode control DC/DC converter that provides fast transient response performance and simple phase compensation setup.

Here are a few features of the DC/DC Converter:

Wide Input Voltage Range
Integrated High-Side MOSFET
Current Mode Control
Adjustable Frequency
Soft Start Function
Over Current Protection (OCP)
Under Voltage Lockout (UVLO)
Thermal Shutdown Protection (TSD)
Over Voltage Protection (OVP)
HTSOP-J8 package

Here are some documents from the manufacturer:

I am considering adding an adjustable DC Power Supply to the kit, Bench Power Supply

rscasny If you plan to include a power supply it should cover the input range of the EVK. Most here have basic PS but not necessarily one that goes that high nor a variable load.

I agree. But I have a budget. That's the limitation. I'm interested in anyone who has a suggestion, though,

My 2¢: I have that capability but I suspect most here don't.

Not too long ago I had to design a DCDC converter for a personal project that needed to handle 0A to 3A pulsed load. Achieving a decent step response took quite a bit of work! This IC could be interesting to test. Maybe I will give it a shot

The Rohm simulation tool is quite nice.. it looks like a normal Spice simulator embedded in a browser, with the circuit and probes all set up. There are "spare" probes at the bottom-right : ) As many of those can be dragged as desired onto the circuit, and new charts appear for them.

If the output could be raised to 5.3VDC it would be a good PS for a portable Rpi from battery or solar power.

Output goes from 1V to 0.97 x VIN V.

I was thinking of using a switching regualtor to serve as a poor man's substitute for a bench top power supply. The wide operating range of this product in terms of both input and output voltages sounds pretty promising.

That would be a good attack vector for this road test. The switch mode kits are always a good hook to improve your electronics skills, while reviewing the design.
