UC1844: Issue with Isense resistor.

santhosh edukula1

Part Number: UC1844

Hi,

We selected uc1844 PWM controller for our application, We are running simulation for the same to verify design parameters. Here we have issue with Isense resistor.

  1. Our current is 0.6A, As per requirement Isense resistor value need to be 1.6ohm but it is working at 600milOhm only.
