Hi
The system's input voltage is 6-4 V, and the TPS62745 output is fixed to 3.3V. The system includes nRF52832 (SOC) and SPI Flash.
The peak load is around ~24 mA (nRF52832 advertising + read/write Flash).
when the TPS62745 input is 4V, the Load Transient Response increase to ~ 270mV and more- see attached picture .
when the TPS62745 input is above 4V, the output ripples are around 20mV which it's OK.
1.Is the TPS62745 can't work without ripples while input 4V , output 3.3V with ~24 mA load ? do i need to replace the TPS62745 ?
2. Is it possible to reduce the Transient Response high ripples? If so, how?
Please advice
Thank you
