| <description>The AL8860 is a hysteresis mode DC/DC step-down converter, | ||
| designed for driving single or multiple series connected LEDs | ||
| efficiently from a voltage source higher than the LED voltage. The | ||
| device can operate from an input supply between 4.5V and 40V and | ||
| provide an externally adjustable output current up to 1A for TSOT25 | ||
| package and 1.5A for MSOP-8EP package. Depending upon supply | ||
| voltage and external components, this converter can provide up to 40 | ||
| watts output power. | ||
|
|
||
| The AL8860 integrates the power switch and a high-side output | ||
| current sensing circuit, which uses an external resistor to set the | ||
| nominal average output current. | ||
| Dimming can be realized by applying an external control signal to the | ||
| CTRL pin. The CTRL pin will accept either a DC voltage signal or a | ||
| PWM signal. | ||
|
|
||
| The soft-start time can be adjusted by an external capacitor from the | ||
| CTRL pin to ground. Applying a voltage of 0.2V or lower to the CTRL | ||
| pin can turn off the output and make the device enter into standby | ||
| state with low current consumption.</description> | ||
