EVM Test Setup
The settings for the test equipment shown in Figure 2–1 are described below:
- Power supply set to 5-V and 1-A current limit connected to IN (J2) and
GND (J3).
- Function generator set to 1 Hz, 25% duty cycle, 0-V to 5-V amplitude
square wave (may require setting of 2.5-V square wave and 2.5-V dc off-
set) with positive side connected to EN (J1) and negative to GND (J4)
- Oscilloscope with the time scale set to 10 ms/div, channel 1 connected to
OUT (J4), and channel 2 connected to EN (J1). Set the oscilloscope to
trigger off of the falling edge of channel 2 of the oscilloscope.
- Appropriately sized resistance for desired output current between OUT
(J4) and GND (J3).
Powering up the device and function generator will result in an oscilloscope
plot similar to the one in Chapter 3.
