Dear Sir

Good days,

How to check TLV62090 boundary current for PFM/PWM switch?

And I have check TLV62090 and TPS62090, these two parts seems P2P, right?

                                       Best regards,

    you can measure the waveform of SW pin. in PFM mode, there is a period that both high side and low side mosfet is off, and SW voltage equal to Vout.

    you are right. the two device is P2P. TPS62090 is high performance. TLV62090 is cost effective. thanks.
