Part Number: LM5180EVM-S05
I trying to make 12Vin (or 24Vin) to 24Vout spec based on LM5180EVM-S05.
※Transformer changed default(YA7889) to the other custom, and the other external components are changed depend on Input/Output specification.
But measured waveform is abnormal, schematic and waveform are attached below.
Please let me know about correction point or any advice.
【Test Condition】
⇒ch4(pink): Vin, ch3(Blue): SW, ch1(Yellow): Iin, ch2(Green): Vout
By the way, 24Vin condition occur unstable Iin.
Vin: 24V, Vout: 24V, Iout: 100mA
※When Iout decrease, unstable Iin become large.
Best regards,
Satoshi
