PRODUCTION DATA
The UCC28C5x-Q1 current sense input connects directly to the PWM comparator. Connect CS to the MOSFET source current sense resistor. The PWM uses this signal to terminate the OUT switch conduction. A voltage ramp can be applied to this pin to run the device with a voltage mode control configuration or to add slope compensation. To prevent false triggering due to leading edge noises, an RC current sense filter may be required. The gain of the current sense amplifier is typically 3 V/V.
