9 Power Supply Recommendations

The power supply for the applications using the LM4510 device should be big enough considering output power and efficiency at given input voltage condition. Minimum current requirement condition is (VOUT * IOUT)/(VIN * efficiency) and approximately 20 - 30% higher than this value is recommended
