9.3 Power Supply Recommendations

The TPS25772-Q1 is a power management device typically operated from an automotive battery, though the power supply for the device can be any dc voltage source within the specified VIN input range. The supply must be capable of supplying sufficient current based on the maximum inductor current in boost mode operation. The input supply can be bypassed with bulk capacitors at the input of the application board to avoid ringing due to parasitic impedance of the connecting cables. A typical choice is an aluminum electrolytic capacitor of 47 to 100 μF.
