LMR14030-Q1: LMR14030SSQDDARQ1 (Spread Spectrum) Inductor Charging and discharging

Part Number: LMR14030-Q1

Dear Sir/Madam,

We are using LMR14030SSQDDARQ1 (Spread Spectrum).

we are using 4Amp, 22uH inductor  output capacitor 220uF/35V, Switching frequency 240KHz.

input 24VDC, output : 9VDC load current : 200mA to 1200mA (Load current changes with LED loads).

our inductor current reaches minimum 62mA and maximum 1018mA  at load current 1200mA. please find attached waveform.  if inductor current becomes zero,  will circuit start malfunction.

thanks
