Macroblock launches high power LED driver IC

Technologies (Macroblock) for high power LED lighting market, launched the IC MBI1801 driver output current up to 1 amps; high output current of the IC special known with different combination of lighting products, and provide a constant current for high power LED, which can avoid the excessive current burned Ang Guigao emergency power LED. MBI1801 using PrecisionDrive and All-Ways-On technology, the user can through an external resistor to set the current, in addition can also be input PWM signal to control the brightness of LED, frequency up to 1MHz, the adjustment range from 100% to 0%. In addition, in order to ensure the reliability of the application of the product, MBI1801 built-in temperature sensor with Protection (Thermal, TP) function and provide heat sink. The temperature sensor chip can detect temperature, when the temperature exceeds 165 degrees C, overheating protection function will be closed to prevent the drive current, temperature is too high; and in the heat sink with TO220-5 package, through the metal gasket of the heat conduction to the printed circuit board in order to increase the cooling capacity, achieve safe disposal of high output current. MBI1801 for different LED lighting products, such as LED and MR16 lighting lamp, flashlight. The All-Ways-On family includes MBI1802 and MBI1816, MBI1804, output current from ma.
