Part Number: TPS2373

We are planning to use TPS2373-4RGWR(Type4) in place of TPS2373-3RGWR(Type3). Can you please guide us regarding what the changes are required to made in design apart from resistor CLSB.

    Hi Aditi,

    Thanks for reaching out.

    TPS2373-3 and -4 are pin-pin chips. Nothing needs to changed besides the CLSB resistor. You can do some minor changes like reducing bulk cap capacitance, changing current sensing resistor, FET adjustment to optimize the DC/DC converter but they are not mandatory.

    Best regards,
