DiodesZetex LED Driver IC, 45 V 100 mA 6-Pin SOT-26

The DidoesZetex monolithically integrated linear LED controller designed to function as a Constant current Regulator (CCR) for linear LED driving. The device operates over a voltage range from 5V to 42V and regulates the output LED current up to 100mA, set by an external resistor. It is designed for driving LEDs in strings and will reduce current at increasing temperatures to self-protect. The low voltage drop during current regulation allows efficient driving of LED strings with a range of forward voltages and supply voltage tolerances. The LED current is adjustable between 5mA to 100mA with an external Resistor. No external capacitor is required for stable operation/The LED dimming is done using PWM.

Supply voltage of 5V to 42V and high power 1W dissipation in SOT26 LED current tolerance of ±5% at 95mA output current Thermal protection reduces LED current at elevated temperature Low typical saturation voltage of 115mV at 50mA
