SN3360GP05E

SN3360 is a buck-topology, continuous inductor current mode LED driver designed for applications where the supply voltage exceeds the forward voltage of a single LED or a series LED string. The input voltage range is 6V to 40V, with an output current of up to 1.2A. The SN3360 integrates an internal power switch and uses high-side current sensing, allowing the average operating current to be set via an external resistor. The output current can also be controlled by applying a signal to the ADJ pin, which accepts either a DC voltage or a PWM signal, providing DC or continuous pulsed output current accordingly. When the ADJ pin voltage falls below 0.2V, the device shuts down and enters a low-power mode. The device is available in a SOT89-5 package.
