9 Power Supply Recommendations

The LM25010 is designed to operate with an input power supply capable of supplying a voltage range from 6 V to 42 V. The input power supply must be well-regulated and capable of supplying sufficient current to the regulator during peak load operation. Also, like in all applications, the power-supply source impedance must be small compared to the module input impedance to maintain the stability of the converter.
