XLT604 is used BICMOS process design of high-performance LED driver PWM control chip. It is the input voltage to 450VDC from 7VDC can effectively drive highlighted within the LED. The chip can be up to 300KHz fixed frequency drive an external MOSFET, the frequency of an external resistor programming decisions. External Highlight LED string constant current mode control, in order to maintain constant LED brightness and increase the reliability of its constant value is decided by an external sample resistance value, changes range from a few mA to 1 amp.
XLT604 driven LED can be adjusted through an external control voltage linear brightness can be adjusted through an external low-frequency PWM mode the brightness of LED strings.
