The new AP880X family is designed to drive series-connected LEDs with a constant current. The new AP880X family supports up to 13 LEDs from the voltage sources between 8V and 48V. The new drivers are suitable for a wide range of high-brightness, general illumination applications, incorporating signage, architectural, emergency lighting and MR16 lamp replacement, ensuring uniform LED brightness and also remove the need for ballast resistors.
For an operating voltage range from 8V to 28V, the AP8800 furnishes a string of seven LEDs with a current up to 350mA, offering a cost effective match for 1W LED systems. For higher output power, the AP8801 generates a drive current of 500mA from an operating voltage of 8V to 48V to support up to 13 series-connected LEDs.
The third product in the driver family, the AP8802, meets the needs of high power 3W LED systems. For an operating voltage range from 8V to 48V, the AP8802 driver offers up to 13 LEDs with a constant LED current of up to 1A. All three devices supply efficiencies up to 92%.
To decrease the stress on LEDs, the new AP880X drivers feature an integrated soft-start function that helps to extend LED lifetime. The new drivers also provide the choice of PWM and DC input dimming control in order to increase design flexibility. All devices are packaged in SOP-8L package. The AP8800 and AP8801 are also available in MSOP-8L and the AP8802 in exposed pad DFN and SOP-8L packages.
