Part Number: LMR51420 Tool/software: Dear Specialists,
My customer is evaluating LMR51420EVM and has questions.
I would be grateful if you could advise.

When the LMR51420YFDDCR is turned on with a light load (about 100mA), the inductor current…
Hi, Joshua,
Thnaks for your reply, we use the full part# is LMR51420YFDDAR and the frequency is 1.1MHz, the LMR51420EVM is based on 500KHz,
so you mean we need add the bulk capacitor in parallel with the ceramic input capacitors for slow down the…
Hi Denisslav, thanks for the answer, in fact the PMF mode justifies the voltage drop of 100 mV at full load (although from the graph it would seem closer to 50mV). So, if I understand correctly, using the FPWM version I would have a more stable voltage…
