Part Number: PMP40766 Hi ,
As a beginner in power supplies, could you please tell me about the parameter design of T1 and T2 in the scheme?
I can't find the specific parameter design of transformers T1 and T2 in the scheme, such as turns ratio, etc. I…

Hi，
May I ask how to test the voltage loop and current loop of the post-stage LLC of PM40766 respectively? When I am testing the voltage loop now, I have soldered the components of the…

Hi,
During no-load operation, the output voltage is 71.4V. When a 30-ohm pure resistive load is applied, the circuit operates normally with the red indicator light on, the fan running, and…

Hi，
In the PFC circuit, can the 47-ohm resistor RF1 under C11 be replaced with an ordinary resistor? If not, can I directly short it to test the voltage across C11? Now, when the input voltage is 220VAC, the voltage across C5 is…

Hi ,
Generally speaking, the dotted terminals (polarity markings) of the transformer in a half-bridge LLC converter are typically the same for both primary and secondary windings. However, in this specific design, the transformer…

HI,
When the LLC circuit is in constant voltage control mode, Vout = 71.4V. When the current decreases to 0.7A, the non-inverting input terminal of U6A should be 0.175V through calculation. The inverting input terminal of U6A…
