      Note 3: On the UCx833 this voltage is defined as the regulating level at the error amplifier inverting input, with the error amplifier
      driving VSOURCE to 2V.
      Note 4: These parameters are first-order supply-independent, however both may vary with supply for +VIN less than about 4V. This
      supply variation will cause a slight change in the timer period and duty cycle, although a high off-time/on-time ratio will be main-
      tained.
      Note 5: With recommended RT value of 200k, TOFF
      ≈ RT CT * ln(Vu/Vl) ±10%.
      Note 6: The internal current limiting voltage has a temperature dependence of approximately -2.0mV/°C, or -2800ppm/°C. The inter-
      nal 2.4
       sense resistor has a temperature dependance of approximately +1500ppm/°C.
