LM5175: External Clock

T Kishi

Part Number: LM5175

My customer has question.

When operating the LM5175 using an external synchronization clock,
Is it OK to sequence "external clock" ⇒ "LM 5175 EN ON"?

Hi Youhao

Please cooperate me.

When using the "SYNC function" in the LM 5175, we recognize that the pulse width is prescribed as 75 to 500 ns.
The customer wants to use an external clock of 380 kHz. Is it possible?
Also, when using at 380 kHz (period = 2600 ns), it is necessary to input a signal with duty = 10% with ON time being 300 ns Is this recognition correct?

Best Regard
