The TPS54286PWPG4 is a dual output non-synchronous Buck Converter capable of supporting 2A output applications that operate from a 4.5 to 28V input supply voltage and require output voltages between 0.8V and 90% of the input voltage. With internally-determined operating frequency, soft-start time and control loop compensation, these converters provide many features with a minimum of external components. Channel 1 overcurrent protection is set at 3A, while channel 2 overcurrent protection level is selected by connecting a pin to ground, to BP or left floating. The setting levels are used to allow for scaling of external components for applications not needing the full load capability of both outputs. The outputs may be enabled independently or may be configured to allow either ratiometric or sequential startup sequencing. Additionally, the two outputs may also be powered from different sources.
● Dual PWM outputs 180° out-of-phase
● Ratiometric or sequential startup modes selectable by a single pin
● Current mode control
● Pulse-by-pulse overcurrent protection
● Thermal shutdown protection at 148°C
● Green product and no Sb/Br
