ZHCSK97B September 2019 – August 2020 TPS61023
PRODUCTION DATA
The TPS61023 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 0.5 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 0.5 MHz.
