JAJSOJ5 October 2023 LP5811
PRODUCTION DATA
The LP5811 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.
