Part Number: PMP21735 Hello!
I am planning on using PMP21735 reference design although I can`t find info about transformer used in reference design (PM2522NL).
Can anyone provide possible alternatives or at least transformer specification?
Hello Monica,
The TIDA-050063 design is meant to charge the capacitors to the same voltage as the Vin supply. It is a hysteretic Buck topology configured as a constant-current source. The inductor current ripple will always "bounce" between a programmed…
Hi Stefan,
That is good news. Thank you for your response. We will go ahead with some prototype boards testing the LM5155. The PMP21735 is also an intersting design though it uses a (seemingly not readily avaialble) transformer as well.
Best regards…
Hello Tim,
BIAS pin can be supplied by an "external" voltage. Please make sure that the BIAS voltage is inside the d/s limits.
May I ask what you need the 972V for?
If the intermediate voltages are not used, why not using a modified flyback…
