LM5041A: Frequency confirm

Derek Zhong
Intellectual 470 points

Part Number: LM5041A

1.Could you tell me the frequency generation mechanism of LM5041A and what can determine the frequency?
2.Is there any other IC the same function as LM5041A but have a high frequency accuracy,please recommend for us

Thank you.

    Hi Derek,

    The voltage on the RT pin is regulated at 2V and an external resistor is connected between the RT and Ground to programme a current which sets the internal oscillator frequency. The formula for the oscillator frequency is on page 12 of the datasheet.

    The UC3827 is an alternative option but I think the oscillator frequency accuracy is similar

    Regards
