According to datasheet, ADP1074 is able to lock on a Sync signal ±10% of the set frequency and the spread spectrum of LT6908 is also ±10% from the set frequency.
It is also mentioned that ADP1074 can take a dithered clock for EMI reduction…
Hi ADI expert,
I'm trying to figure out about the Rmode calculate of ADP1074, according to ADP1074 datasheet page22 shows equation Rmode=(IPEAK_LLM x CSgain + 0.8) / Imode. The parameter only have "current" and "CSgain" but how to get the "R" value?…
I designed a 60-watt converter with Active Clamp flyback topology by using ADP1074, with (18-36)input and output (±24V,1.5A for each output ) and switching frequency is 250KHz.winding ratio is 4:7 and I use a mosfet in positive line and a diode…
We are testing the evaluation board "ADP1074-evalz-ug-1115", controlled by ADP1074. In its datasheet, it is said about the pin SYNC:
"The SYNC frequency must be within ±10% of the internal oscillator frequency set by the RT pin…

According to datasheet, there are only 4 steps on dead time setting, Are there formula to calculate dead time but not list in datasheet? Or ADP1074 dead time only have 4 steps and no other values can be set? Thanks for your reply.

Yes, you can set Rt to 600kHz then apply a 625kHz to the sync pin.
I would like to use the ADP1074 for a 24V(18V-32V) input, 24 V output isolated DC/DC.
I think a winding ratio of 1:2 should be fine?
Power is 80W, and I would like to switch at 500 KHz in order to keep the transformer as small as possible.
But how do…
I would like to design an Active Clamp Forward for 100W using the ADP1074.
For evaluation purposes I am currently supplying the IC by an external voltage source on the primary and secondary side (VIN, EN, VDD2). Apart from that I only connected an appropriate…
