• RE: Spectrum spread for ADP1074 (LT6908)

    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…

  • Can you clarify how to calculate the Rmode resistor of ADP1074?

    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?…

  • design with adp1074

    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…

  • ADP1074 Range frequency Syncronization

    Hello,

    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…

  • ADP1074 dead time setting

    Hi Sir,

    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.

    Regards,

  • ADP1074 programmable dead time

    Hi,

    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 it only have 4 steps can be set? Thanks for your reply.

  • RE: ADP1074 Maximum Frequency

    Hi 

    Yes, you can set Rt to 600kHz then apply a 625kHz to the sync pin.

  • ADP1074 Main transformer induction.

    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…

  • Minimum external components for ADP1074

    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…
