Description  
The U6084B is a PWM-IC with bipolar technology designed for the control of an  
N-channel power MOSFET used as a high-side switch. The IC is ideal for use in the  
brightness control (dimming) of lamps such as in dashboard applications. For constant  
brightness, the preselected duty-cycle can be reduced automatically as a function of  
the supply voltage.
