Hello

I Request the Design review of follow schematic.

Condition :

Input Voltage : 1.8V ~ 5V

Output Voltage : 3.3V

Output Current : Normal(40mA ~ 80mA) / Peak(<300mA)

if using the Power save mode, Is it only PS Pin connect the LOW?

Best regards.

    Hi Louis,

    thank you for using our device!

    Input and output caps C9 and C6/7 look ok. Consider putting them as close as possible to the device in your layout.

    VINA and C8 are forming a filter. This is used to avoid that spikes on VIN go directly through to EN/PS, so it is better to connect EN/PS to VINA like in the application recommendation in the datasheet.

    Regarding PS mode, you are correct. PS/SYNC pin neds to connected to GND.

    Hope this helps.

    regards,

    Moritz
