GENERAL DESCRIPTION

The SM8205 is a current mode control wide-input voltage (8V to 48V) LED driver IC specifically designed to power one or multi-strings of high power LEDs. The 10V gate driver allow the use of standard level MOSFET. The low voltage 5.0V VCC is used to power the internal logic and also acts as a reference voltage to set the current level. An external resistor sets the adjustable switching frequency of the SM8205.
