9 Power Supply Recommendations
The LM5176 is a power management device. The power supply for the device is any dc voltage source
within the specified input range. The supply should also be capable of supplying sufficient current based on
the maximum inductor current in boost mode operation. The input supply should be bypassed with additional
electrolytic capacitor at the input of the application board to avoid ringing due to parasitic impedance of the
connecting cables.
