Overview:
+0$ is a current modulating circuit operating from 2.85V to 6V circuit, with constant output current up to 1.5A, can be used to drive including Various types of light-emitting diodes, including white light-emitting diodes. +0 $ The LED terminal current is set by an external resistor, the current range range from 30mA to 1.5A. Power transistors are integrated inside the chip, Greatly reduces the number of external components. The chip also integrates There are circuits such as status registers and oscillators, in the key input pins With the cooperation of the timing capacitor connection pin, +0 $ can be controlled LED in three of the four states of off, strong light, weak light and strobe cycle between one or four states, ideal for flashlight application. Other features include chip temperature modulation, chip enable input entry etc. +0 $ Available in a thermally enhanced 8-pin SOP8 package.
