    Hi Richard Li,

    The power supply voltage is OK. Which bit of the StatCON Register is set? Is it Bit 4?

    The STATCON_Register is used by the over-temperature detection. Have a look at chapter...

    Hello Zuhaib,

    Please keep in mind that a high side driver requires the bootstrap capacitor to be charged in order to turn on the switch. This means that driver needs to be used in such a way that...

    Hello Zuhaib,

    It's a bit difficult to read the details in the photo snapshot that you provided, but we assume that the serial resistor is 10 Ohms. You used the additional diode to do the...
  8. reply to: changing the gate turn on and off resistor to reduce the switching losses

    Not only by changing the gate resistors is the efficiency affected, but also the drain to source peak voltage during turn off as well as the EMI behavior of the converter. This is a very iterative...

    When the PFC is in working Continuous Conduction Mode:
    - Conduction losses
    - Turn on and off (Switching) losses
    - Gate losses
    - Output capacitance (i.e. Co(er)) losses

    When the PFC is in...

    Hi Kal,

    While it is still possible to perform a socket-type programming that you mention on our controllers via pre-programming at the manufacturer's site, this has become more of a practice of...
