1. 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.
