switching Node monitoring

Krishna

Part Number: LMR14030

LMR14030 regulator is design to operate at 600KHz with pull down resistor 41.2Kohm. is it possible to measure switching waveform of 600khz at SW pin.

Yes. Though designing Rt, you can design to 600kHz and measure switch node.

sure

if i monitor SW pin(8) in LMR14030S can i measure 600KHz waveform. or

How to measure this switching frequency to observer any ringings etc?

Use the probe test SW waveform with 20M bandwidth.
