9 Power Supply Recommendations

The LM2852 is designed to operate from various DC power supplies. If so, VIN input must be protected from reversal voltage and voltage dump over 6.5 V. The impedance of the input supply rail must be low enough that the input current transient does not cause drop below VIN UVLO level. If the input supply is connected by using long wires, additional bulk capacitance may be required in addition to normal input capacitor.
