    Does having high thermal resistance in a diode SMT package reduce efficiency?

    Hi All, Having an almost philosophical thought regarding poor thermal dissipation of surface mounted Silicon carbide diodes with thermal pads. I tested my resonant converter and expected >90% efficiency but only get around 70% at full-load. I put a FLIR camera onto the board and noticed that...

    Enable DCDC with PowerGood

    Hi!! I'm working with a BuckRegulatro from Vicor, PI3423-00-LGIZ . And I want to use the PowerGood signal to disable another DCDC ( with an ON(3.3V) or OFF(GND) signal). The question is that the PowerGood of the PI3423 is HighImpedance (operating and no stable) or Voltage output (when the...

    need help with bulding a DCDC Buck Circuit (multi output)

    Hello , I have a project that I wnat to build for him a DCDC back circuit right now I use 4 XL405 DC-DC , but I want to create my own circuit (this is for a small project I have and I will create ~ 100 of it) the input 24-35V the 4 output voltage are: 12V 2A 24V 2A 5V 4A 3.3V 1A I don't...
