LED昇圧定電流レギュレータ

昇圧レギュレータは、複数のLEDを直列駆動するために必要な高電圧を供給し、正確なLED電流マッチングを保証します。
STは、低ノイズで調光範囲が広く、フットプリントが小さなシングルチャネルおよびマルチチャネルの高効率昇圧LEDドライバを提供しています。また、過電圧および過電流保護、サーマル・シャットダウン、LEDアレイ保護などの保護機能も搭載しています。
 
 

3A LED driver with integrated DC-DC converter for automotive applications

The new ALED6000 is a single-chip automotive LED driver with integrated DC/DC converter designed to source up to 3 A on a single strip LED and to operate with a wide input-voltage range of 4.5V to 61V, which makes it the ideal choice for automotive systems.

 

Housed in a HTSSOP16 Package, the ALED600 is suitable for exterior lighting such as daytime running lights, headlights, rear lights, stop lights, and turn signals, as well as interior lighting.

 

Evaluation board is also available to help developers consolidate their designs.

Automotive LED driver with embedded DC-DC converter controller

The ALED7709 is a brand new 4-channel LED driver suitable for automotive backlighting and interior lightning applications like: infotainment displays, Head-Up Display (HUD), instrument lights, clusters, ambient lighting, and adjustable LED strings control.

Packaged in a QFPN 5X5 24L wettable flank, the ALED7709 is provided in two versions:

-          ALED7709A, dedicated to bus driven mode (BDM) through an I2C serial interface.

-          ALED7709B, suitable for applications where the standalone mode (SAM) is required with dimming controlled by a PWM input signal.
