Diodes new LED drive AP880X series reduced component overhead

Diodes company launched the new LED driver IC (IC) series AP880X to significantly reduce the number and size of external components required for the drive circuit. AP880X buck DC-DC converter requires only 4 components to support, can work at up to 600kHz switching frequency, so you can use smaller, lower cost inductors and capacitors.

The AP8800 series operating voltage range of 8V to 28V, can provide a series of 7 LED current up to 350mA, thus reflecting the cost effectiveness of 1W LED system. For higher output power, another device AP8801 can generate 500mA drive current at 8V to 48V operating voltage, supporting up to 13 series LED.

Third AP8802 devices can meet the needs of higher power 3W LED system, operating at 8V to 48V voltage, can provide up to 1A of up to LED constant LED current. The efficiency of these three devices are up to 92%.

In order to reduce the LED stress, the AP880X driver uses the integrated soft start function, which is helpful to prolong the service life of LED. In addition, the driver can provide a pulse width modulation (PWM) and the DC input dimming control, reflect more flexibility in the design. All devices use the industry standard SOP-8L package, where AP8800 and AP8801 are also MSOP-8L packages, while the AP8802 has exposed solder DFN and SOP-8L packages.
