applications. The LX1995-x is an FB pin which maintains constant output  
adjustable step-up boost converter. current independent of input voltage  
The LX1995-x can switch up to 2MHz and LED forward voltage (VF). LED  
allowing designers to use a low cost, dimming is accomplished using a PWM  
small inductor and filter capacitor.  
The driver supports a wide input
