Other Parts Discussed in Thread: LM27403
Hi,
a customer I support just received their proto boards back using the LM27403.
The datasheet claims that the internal startup delay for internal calibration is 512 clock cycles. In their case (700KHz) it should be 0.73mS.
They however measure a delay between enable and beginning of softstart a delay of 4.7mS.
What can be the reason of this apparent too long delay.
