8.2.2.4 Current Sense
The CS pin receives an input signal representative of its transformer’s primary current, either from a current
sense transformer or from a resistor located at the junction of source pin of the primary switches, as shown in
Figure 27 and Figure 28, respectively. In both the cases, the filter components RF and CF should be located as
close to the IC as possible, and the ground connection from the current sense transformer, or RSENSE should be
a dedicated trace to the appropriate GND pin. Please refer to the Layout section for more layout tips.
The current sense components must provide a signal > 710 mV at the CS pin during an over-load event. Once
the voltage on the CS pin crosses the current limit threshold, the current sense comparator terminates the PWM
pulse and starts to charge the RES pin. Depending on the configuration of the RES pin, the LM5045 will
eventually initiate a hiccup mode restart or be in continuous current limit.
