ZHCSJB0D January 2019 – July 2021 TPS61022
PRODUCTION DATA
The TPS61022 switches at a 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 0.6 MHz to improve the efficiency and get higher boost ratio. When the input voltage is below 1 V, the switching frequency is fixed at a quasi-constant 0.6 MHz.
