Although the PMP9398 reference design focuses on fixing conducted emissions in the 150 kHz to 108 MHz frequency band, the same circuit techniques solved our radiated problem in the 30 - 400MHz range:
parallel smaller caps combination (1.5nF, 10nF, 100nF…
Hi, Blaz
It looks the C1 and C4 affect the stability, let's make the IC work more stable first.
Comments:
1. What is the value of C7 and C10?
Suggest changing the compensation circuit same as Webench design.
2. For the input capacitors, what is the…
