LM53603-Q1: design review

Part Number: LM53603-Q1
Other Parts Discussed in Thread: LM53603, LMR43610-Q1

Tool/software:

In the design of the LM53603 EVM, Vin has three 10uF capacitors, and Vout has three 22uF capacitors. Due to limited PCBA space and my application requirements (Vin=9V, Vout=3.3V, Imax=300mA), is it possible to remove two of the 10uF capacitors on Vin and two of the 22uF capacitors on Vout?

  • Hello, The input capacitors can be removed, but, for the output capacitors, only 1 can be removed to ensure device stability.

    LMR43610-Q1 could be considered for a future design which requires a smaller solution size.
