TPS543834.5V to 28V Input, Dual 3A Outputs, 300kHz Step-Down Converter with Internal Compensation | Power Management (PMIC) | 3 | Active | The TPS54383 and TPS54386 are dual output, non-synchronous buck converters capable of supporting 3-A output applications that operate from a 4.5-V to 28-V input supply voltage, and require output voltages between 0.8 V and 90% of the input voltage.
With an 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 4.5 A, 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 that do not need the full load capability of both outputs.
The outputs may be enabled independently, or may be configured to allow either ratio-metric or sequential startup sequencing. Additionally, the two outputs may be powered from different sources.

The TPS54388C-Q1 device provides accurate regulation for a variety of loads with an accurate ±1% voltage reference (Vref) over temperature.
The integrated 12-mΩ MOSFETs and 515-µA typical supply current maximize efficiency. Entering shutdown mode using the enable pin reduces shutdown supply current to 5.5 µA, typical.
The internal undervoltage lockout setting is at 2.45 V, but programming the threshold with a resistor network on the enable pin can increase the setting. The slow-start pin sets the output-voltage start-up ramp. An open-drain power-good signal indicates when the output is within 93% to 107% of its nominal voltage.
