SCM1331A 40V Input Voltage， 2A LED Driver Packaging Features  Wide 4.5V to 40V Input Range  Adjustable Switching Frequency from 200kHz to 1500kHz  Output Current up to 2 A  Internal Soft-Start  200mΩ High-Side MOSFET  4μA Shutdown Current  Over-current Protection, and Thermal Protection Product Package: eSOP-8 (see “Ordering information” for details) Application    High Power LED General Lighting Constant Source Description The SCM1331A is a step-down regulator to deliver a constant current of up to 2A to LEDs, with a wide input range 4.5V to 40V and 4μA ultra-low shutdown current. Current mode control and 200mV reference is applied for fast loop response and easy compensation. The switching frequency in 200kHz~1500kHz, it is programmable with an external resistor, and this allows the device to be used with minimum external components to achieve low output voltage ripple. Soft start is implemented internally to reduce external components. The EN pin is used to realize PWM dimming. The SCM1331A is used to drive single or multiple series, monochrome or infrared LED arrays, such as in cameras.The device has built-in thermal protection and short protection, and is available in the eSOP-8 package（4.9mm × 3.9mm ×1.4mm）.
