Peak Output Current Measurement Using 180nF Load

The output can be configured to measure peak output current by moving the jumper from J6 to J7. This
jumpers in a 180 nF load capacitor, C15, which can be used to indirectly measure the output current as
seen in the

Understanding Peak Source and Sink Current Parameters Application Note

(SLLA387). Input

PWM is set to 200 Hz to avoid excessive power dissipation in the driver.
