Tool/software:
Hi
I datasheet it says that "Adjustable switching frequency (200 kHz to 1.2 MHz)"
But again table 2 of the data sheet suggests a defined Fsw for a particular output.
Can I program my Fsw other than this table or I have to follow the table.
Because I want to set 550kHz as my Fsw but the table suggests 250kHz,
even if I go with 250kHz the webench simulation the phase margin is 46. So two questions.
1. can I improve my phase margin by any external circuitry at 250kHz
2. or can I program my Fsw to 550kHz using Rrt resistor.
Regards,
Raju
