PT4211BE23E 5V-36V 600mA High Brightness Constant Current Step-Down LED Driver IC - SOT-23-5

Datasheet

PT4211B is a step-down constant current source in continuous inductor current conduction mode. Specifically designed for driving 1-3 LEDs in series. PT4211B Acceptable input voltage range is from 5V to 36V, output current is adjustable to 600mA max.

PT4211B has a built-in power switch and adopts high-end current sampling method. Set the average LED current through an external resistor. DIM pins can accept Analog dimming and wide range PWM dimming. When the voltage of DIM is low When, the power switch is turned off and PT4211B enters standby with extremely low operating current. state.
