Other Parts Discussed in Thread: UC3844,
Hi
How can we check the open loop test of uc3842/uc3844?
I gave
Vcc = 17V,
Vfeedback = 2.5V externally
Isense = 0.5V externally
When applying all these voltages, the output pulse I'm getting has max pulse width(for uc3842 - 98% & for uc3844 - 48%). By varying Vsense and Isense pulse width is not varying. Why pulse width is not varying by changing these voltages?
