SNVSC74 September 2023 LP5813
PRODUCTION DATA
The device is designed to operate from an input voltage supply range from 0.5 V to 5.5 V, with minimum 1.8V start up input voltage. This input supply must be well regulated. If the input supply is located more than a few inches from the converter, additional bulk capacitance is required near to the ceramic bypass capacitors. A typical choice is a tantalum or aluminum electrolytic capacitor with a value of 100 μF.
The LP5813 can also work normally by powering from VOUT with 2.7 V to 5.5 V voltage range, to bypass the integrated boost converter. In direct drive mode or mix drive mode, an external LED supply with 2.7 V to 5.5 V voltage range is supported to power up the LEDs in direct drive configurations.
