ADVANCE INFORMATION

Application Hint:
Temperature drift of the output carrier frequency can be cancelled by measuring both a PWM period and
the on-time of PWM (Duty) at the same time. Since both periods vary in the same direction, computing the
ratio between these values at each PWM period gives consistent measurement of the current feedback
over the temperature drift.
