1.3 Test Setup

Testing is performed with 24-V input on VIN, and PWM applied to IN+. VEE is tied to the primary side GND, and all signals were probed relative to primary side GND. Jumper J1 is connected from pin 1-2, J3 is connected from pin 2-3, and J4 is connected from pin 1-2. All testing in this report was done with a 100-nF capacitive load populated on C19.
