  • RE: UCC2808-2: Repeated fault analysis

    Hi Alon, It meant ambient temp rather than junction temp. 87C Ambient temp exceed max recommended operating range of UCC2808-2. Can you lower the ambient temp to see where the part starts switching? For the UCC2808A-2Q1, I compared it against UCC2808A…

  • RE: UCC28C40: Selection of PWM Controller and Reference Design

    Resolved
    Hi, UCC28C40 is not for push-pull. UCC2808A-1 or -2 is. LM25037 is another one can be considered.

  • RE: UCC28089: Application note and replacement recommendation for UCC28089

    Hi, Resistor for CS is to match over current to CS threshold in the datasheet. ZCD is not a pin of this IC. No COMP pin. UCC2808A-1 or -2 are recommended.

  • RE: LM5045: Seeking Recommendation for PWM Controller for 300W Isolated Full-Bridge DC-DC Converter for EV Application

    Hi, 1. LM5045 does not have automotive graded parts. Also we do not have a part like LM5045 with automotive grade. We have two parts LM25037-Q1 and UCC2808A-1Q1, or UCC2808A-2Q1, but these need to have external bridge drivers to make full bridge converter…

  • RE: UC1901: Alternative for new designs

    Hi, It looks UCC2808A-1, or -2 OUTA and OUTB should produce similar - what difference do you see from UCC2808A-1, or -2 that cannot meet your requirements? TL494 maybe another device can be considered.

  • RE: LM5035C: High-Voltage Half-Bridge Driver with inbuilt Oscillator

    Resolved
    Hi, Our solution is PWM controller + Driver. For 600V applications, driver UCC27712 can be used along with a PWM controller, such as UCC2808A-1 or -2 which is ok to operate in open-loop.
