SNVSC74 September 2023 LP5813
PRODUCTION DATA
The LP5813 switches at quasi-constant 1-MHz frequency when the input voltage is above 1.5 V. When the input voltage is lower than 1.5 V, the switching frequency is reduced gradually to 0.5 MHz, which improves the boost efficiency and gets higher boost ratio. When the input voltage is below 1 V, the switching frequency is fixed at quasi-constant 0.5 MHz.
