Hello,
I am designing a new board, where I need to have a stable 5V output. The load will be around 100 mA with spikes up to 1,3 A for approx. 10 milliseconds (Iridium 9602 module). The voltage drop during the spike should not be more than 0.2 Volts.
As a power source I have a Li-Ion battery, which will be most of the time at a full charge (I have a charger IC for it).
Could you please check, if my layout seems OK for such application?
It is a 2 layer PCB with GND on top and bottom layer.
Converter will be switched on/off using MOSFET transistor, which will be connected to EN pin (can be seen at the bottom of the layout picture).
LBI and LBO pins are not used, as well as SYNC pin (connected to IN to disabled power savings).
C6 and C7 are ceramic input caps with low ESR, the same for C8.
C9 is electrolytic cap: https://cz.mouser.com/ProductDetail/Panasonic/EEE-FT1A152AP?qs=1Gb%2FpduDpOCg5B5B1I92vw%3D%3D
