ZHCSNP9B March 2021 – October 2021 TPS61379-Q1
PRODUCTION DATA
When the input voltage is above the UVLO threshold and the EN pin is pulled above 1.2 V, the TPS61379-Q1 is enabled. The TPS61379-Q1 starts to monitor the FB pin. With a typical 400-μs delay time after EN is pulled high, the TPS61379-Q1 starts switching. There is an internal built-in start-up time, which is typically 2.5 ms, to limit the inrush current during start-up.
