I am designing a PWM with UC2825 chip with the open loop laboratory text fixture recomended by TI in the application note. Making measurements in the chip´s pins everything seems to be OK, but there are not signals on the output pin´s.
Please, somebody could help me in order to discover why the UC2825 seems to be inactive?
Which thing in the input signals could be producing this state?
Thank you very much.
