OUTA and OUTB are the primary switching outputs of the controller. Due to the roughly 150-mA peak current capability of these outputs, an external gate drive solution will be needed. For buck and single ended isolated converter applications, OUTA provides the gate control signal for the main switch in the topology. For push-pull applications, OUTA and OUTB are both used to provide control signals to the main primary signals. Note that OUTB is only active when the duty cycle limit is set to 50% by connecting DCL pin to AVSS. OUTA and OUTB are not perfectly matched and will vary based on the COMP voltage in a given switching cycle.
