LMR14020: How to calculate IOL/IOH?

Part Number: LMR14020

Dear team,

Please kindly tell me how to find the IOH and IOL in the LMR14020 design instructions, or which values are they in the datasheet? I didn’t see the IOH and IOL parameters in the specification sheet. Thanks!

    Hi Zoe

    This equation is to select the Cout so that the Vout undershoot/overshoot is not too large during load transient, for example, when I_out jumps from 0 to 2A(the rated Iout in customer's application), the Vout will have a undershoot. IOH is 2A, IOL is 0.

    Thanks and best regards.
