ADDTEK

Analog ICs, LED drivers and voltage regulators

About the manufacturer

ADDtek Corp. is a Taiwanese semiconductor brand best known for analog ICs and power-management solutions. Its product legacy includes devices for LED driving, voltage regulation and current control.

Among its most recognizable devices are AMC-series ICs used as simple constant-current regulators and LED drivers. These parts are useful in designs where a low external component count, compact package and straightforward current setting are important.

ADDtek solutions are mainly associated with lighting and power electronics. Their analog architecture also makes them suitable for compact power modules, portable electronics and designs requiring simple, stable current regulation.

Applications

ADDtek ICs are primarily intended for simple, compact power-management and LED-driving circuits. They are well suited to applications where small size, stable current or voltage regulation and straightforward integration into the end device are important.

• LED lighting – current regulation in LED modules and compact luminaires.
• Flashlights and portable lighting – constant-current driving of power LEDs.
• Consumer electronics – power and backlight circuits.
• Signal modules – LED control in industrial and consumer devices.
• Auxiliary power rails – linear voltage or current regulation in simple power circuits.
• Electronics prototyping – easy-to-apply ICs for compact LED projects.
