Other Parts Discussed in Thread: TPS54340-Q1
Hi TI support,
We are using TPS54340B-Q1 in one of application with design details of VIN=12V to 18V & Iout max=2.5A, Vout=4V, Fsw=917KHz. Input voltage is fixed at 15V. There appears jitter in switching frequency varying from 878KHz to 930KHz.
We tried varying resistive load from 0.74A to 1.6A but jitter remained persistent. Pls advice ahead for this issue.
Attached are the schematic snapshot & oscilloscope waveform of jitter.
Thanks,
jagdish
