9 Power Supply Recommendations

The LP5524 is designed to operate from an input supply range of 2.7 V to 5.5 V. This input supply must be well

regulated and able to provide the peak current required by the LED configuration without voltage drop under load

transients (enable on/off). The resistance of the input supply rail must be low enough such that the input current

transient does not cause the LP5524 supply voltage to droop below 2.65 V. Additional bulk decoupling located

close to the VIN pin may be required to minimize the impact of the input-supply-rail resistance.
