Hi, my name is Jason Arrigo. I'm an applications engineer supporting TI's power modules. Today, I'm going to be demonstrating the EVM of the TPSM84205 power module. This device is ideal for any 12-volt or 24-volt applications, including industrial applications. So let's look at some of the features of this device.

This device is part of a family of three devices that are packaged in TO-220 footprint. They're high-efficiency linear regulator replacements. They have an input voltage range of 4.5 volts to 28 volts, with fixed output voltages of 3.3 volts for the TPSM84203, five volts for the TPSM84205, which is the device I'll be demonstrating today, and 12-volt output for the TPSM84212.

All three devices are capable of delivering 1.5 amps of output current. They have ultra-low quiescent current, and meet Class B radiated emissions. All three of these devices are pin-compatible with TO-220 footprint linear regulators. These devices have higher efficiency than the linear regulators, so let's look at the comparison of this device versus a linear regulator.

So here we show a graph of the TPSM84205 versus a linear regulator. The top graph is the efficiency of the TPSM84205 operating from an input voltage of eight volts with an output voltage of five volts. And the bottom graph is the efficiency of a linear regulator with the same input and output voltage conditions. As you see, the TPSM84205 has much better efficiency than the linear regulator.

So now, this graph here shows the efficiency of the same devices, now with applying an input voltage of 12 volts, and an output voltage of five volts. And you'll notice here that the efficiency has dropped greatly with the linear regulator, but for the TPSM84205, the efficiency is about the same. And now, increasing the output voltage-- or the input voltage to 20 volts shows the efficiency hit that the linear regulator takes in this condition, where the TPSM84205 remains high.

So the benefits of higher efficiency are lower input current into the power supply and better thermal performance, which means the device will run much cooler. So now let's take a look at the EVM and the connections.

So here we see the TPSM84205 on its EVM. I'm going to be demonstrating the EVM on this board at a different angle just to be able to show the connections better.

So I have an input supply connected and a load connected to the EVM already. The input voltage is connected to the input terminal block, and the load is connected to the output terminal block. There are also test points for monitoring input voltage and output voltage, and these are meant to be connected to a digital voltmeter. They're not meant to be connected to your input voltage or your load, because the traces aren't big enough to handle the current.

There are also test sockets for monitoring the input voltage ripple and output voltage ripple and transient response. And there are also footprints for extra components, for extra output capacitors and input capacitors. Additionally, on the bottom of the board are more footprints for components for both input capacitors and output capacitors, as well as input and output filter components.

So with that, you should be able to quickly and easily evaluate the TPSM84205 EVM. For more information, go to ti.com/powermodules, and thanks for watching.
