DS125DF1610: Any requirements for VDD ramp rate for power-up?

Part Number: DS125DF1610

Are there any requirements for the ramp rate of VDD? The EVM has Do Not Populate for the DC/DC circuit, but it would be 10msec if the values shown in the schematic were to be populated.

Hi Mike,

There is no hard specification for power ramp rate. Internally the DF1610 will wait and do nothing until internal "power good" levels are achieved. Any controlled ramp rate from a DC - DC converter will work just fine.
