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.
