The controllers in the TPS7H500x-SEP series either have a single primary output (OUTA) or dual primary outputs (OUTA and OUTB). Table 8-2 below shows the primary switching outputs that are available for each of the devices. Due to the roughly 150-mA peak current capability of each primary switching output, an external gate drive solution is recommended. For those controllers that support buck and single ended isolated applications (TPS7H5005-SEP, TPS7H5006-SEP, and TPS7H5007-SEP), OUTA provides the gate control signal for the main switch in the topology. For push-pull and full-bridge applications, OUTA and OUTB both provide control signals for the main primary switches. Note that OUTB is only active when the duty cycle limit is set to 50% by connecting DCL pin to AVSS, and this DCL option is only valid for TPS7H5005-SEP and TPS7H5008-SEP (see Duty Cycle Programmability for more details). For the two output controller options, OUTA and OUTB are not perfectly matched and will vary based on the COMP voltage in a given switching cycle.
