  Elliott Potter

  Hi! OK I tried a couple of things. First, I replaced C13 from 120uF to 200uF; it didn't seem to have any impact. Next, I removed D5 and R3, and powered the UCC2813 from a benchtop supply (10V, current limited to 50mA). I applied AC and then powered…

  Steven Mappus1

  Andreas, TI general purpose, current mode PWM controllers can be set up for VMC by feeding the RAMP into the CS pin and they are not topology specific so they can be used for flyback, forward, buck, boost, etc. Configuring a CMC for VMC is a feature detailed…

  Peter Meaney

  Hi Michael, The UCC28C4x and UCC2813-x devices are normally used in secondary side regulated designs which use a TL431 and opto-coupler to feedback the error signal. In these designs it should be possible to get better than +/-5% total regulation of the…

  Zhou, For the UCC2813-0, UCC2813-2 & UCC2813-3, Dmax = 100%, for these versions OUT pin Fsw= Fosc. For the UCC2813-1, UCC2813-4 & UCC2813-5, Dmax = 50%, implemented using an internal toggle flip-flop. So for these versions, Fsw = 0.5 * Fosc.…

  Hi Dexter, UC2813 has the same pin configuration as the UC2842/3/4/5 family. there is a detailed section in the datasheet for finding the voltage feedback loop compensation. The section is 9.2.2.10, Voltage Feedback Compensation, on page 25 of the datasheet…

• RE: UCC28740: High Vout design check

  

  Ulrich Goerke

  Hello Edward, Based on this rather limited set of requirements, the tentative answer is YES. Can you please clarify if the input voltage Vin is AC or DC? If it is DC, then yes the UCC28740 can readily support that spec since the HV input is rated…
