3.2 Layout Considerations

The IN and OUT pins of U1 can carry significant current; so, traces to these pins must be of suitable

length and width to minimize the voltage drop to the load. Locate the 0.1-μF bypass capacitors close to

the IN and OUT pins of U1.

4 EVM Setup

4.1 Recommended Test Equipment

The following test equipment is recommended:

• Two-channel storage oscilloscope

• Current probe

• Voltage probe

• 5 V at 5-A power supply

• Volt-ohm meter

• A passive or active load

4.2 Measuring Current Limit

The user is advised to read the applicable data sheet before using the EVM.

Figure 6 shows the EVM test setup for measuring current limit. The power distribution switch is enabled

into a short circuit for this measurement. Figure 7 shows the current waveform for
