7.3 Power Supply Recommendations

The TPS56837H and TPS56837HA are designed to operate from input supply voltage in the range of 4.5V to 28V. Buck converters require the input voltage to be higher than the output voltage for proper operation. Input supply current must be appropriate for the desired output current. If the input voltage supply is located far from the TPS56837H and TPS56837HA circuit, TI recommends some additional input bulk capacitance.
