PRODMIX
The MCF8315C provides the option to configure the output PWM switching frequency of the MOSFETs through PWM_FREQ_OUT. PWM_FREQ_OUT has configurable range of 15-60 kHz. In order to select optimal output PWM switching frequency, user has to make tradeoff between the current ripple and the switching losses. Generally, motors having lower L/R ratio require higher PWM switching frequency to reduce current ripple.
