AL8860 40V 1.5A BUCK LED DRIVER
Description
Features
AL8860 40V 1.5A BUCK LED DRIVER
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 standby state with
low current consumption.

AL8860 40V 1.5A 降壓型 LED 驅動器
產品說明
AL8860 是一款採用遲滯模式控制的 DC-DC 降壓型轉換器，專為從高於 LED 正向電壓的電源電壓，有效率地驅動單顆或多顆串聯 LED 所設計。元件可支援 4.5V 至 40V 的輸入電源，並可透過外部設定輸出電流；TSOT25 封裝最高可達 1A，MSOP-8EP 封裝最高可達 1.5A。依據輸入電壓及外部元件配置不同，此轉換器最高可提供 40W 的輸出功率。
AL8860 內建功率開關及高側輸出電流感測電路，透過外部電阻設定額定平均輸出電流。
調光功能可透過 CTRL 腳位輸入外部控制訊號來實現。CTRL 腳位可接受 DC 電壓訊號或 PWM 訊號。軟啟動時間可透過在 CTRL 腳位與接地端之間連接外部電容進行調整。當 CTRL 腳位施加 0.2V 或以下的電壓時，可關閉輸出，使元件進入待機狀態，並維持低電流消耗。
