TPS55010: Questions of TPS55010

Part Number: TPS55010
Other Parts Discussed in Thread: LM25018

Hi everyone,

I have some questions as follows , thanks.

Q1 :  IC is TPS55010 , what value is this I-HSCL ?

Q2 : Whether below calculate can used with above calculate portion ?


        LM25018 calculate

Q3 : Ripple current suggestion value ? If have the minimum Ripple current then we can calculate the Lp (max)


  • Hi Han,

    Q1:  I-HSCL is the high side switch current limit, 2.75 A typical, 2 A minimum

    Q2 and Q3:  Do not use any design equations from LM25018.  LM25018 is a non-isolated buck converter.  Use only the design information from the TPS55010 datasheet.
