Supply boost IC / QX2305 / SOP8 package an authorized agent of the original guarantee

Overview QX2305 is a high efficiency, stable and reliable high-brightness LED lamp driver control IC, built-in high-precision comparator, off-time control circuit, constant current drive control circuit, especially for high-power, high brightness multiple LED strings constant current driver. QX2305 uses a fixed off-time control mode of operation, the operating frequency up to 2.5MHz, allows external inductor and filter capacitors, size reduction, efficiency. off-time minimum time can be set by external resistors and inductors, the operating frequency is changed according to user requirements. EN end increase in the PWM signal to adjust the brightness of LED lights. By adjusting the external resistors to control high-brightness LED lamp drive current, the LED lamp brightness constant to achieve the desired brightness, the brightness of the LED lamp flows through the high current from a few milliamperes to one ampere change. Feature programmable drive current High efficiency: up to 90% over a wide input voltage range: 2V ~ 400V high operating frequency:> 1.5MHz operating frequency is adjustable: 500KHz ~ 1.5MHz drive LED lights feature strong: LED light string from one to dozens of high-brightness LED lights Dimmable: EN end by PWM, adjust the brightness of LED lights use battery-powered LED light string LED lights Cup large display screen high-brightness RGB LED lights LED flat panel display backlight control universal constant current constant current charger source
