DIODES Incorporated LED Drivers ZXLD1366EN8TC

The ZXLD1366EN8TC is a continuous mode inductive step-down converter designed for driving single or multiple series connected LEDs from a voltage source ranging from 6V to 60V. It provides an adjustable output current of up to 1A, making it suitable for various LED applications such as industrial lighting, illuminated signs, and emergency lighting. This device is qualified to AEC-Q100 Grade 1, allowing operation in ambient temperatures from -40¬8C to +125¬8C. It features high-side output current sensing with an external resistor for setting the nominal average output current, and the output current can be adjusted using an external control signal on the 'ADJ' pin. Enhanced dimming resolution is achievable through PWM signals applied to the same pin, with a resolution of up to 1000:1. The ZXLD1366EN8TC boasts high efficiency, reaching up to 97%, and supports switching frequencies up to 1MHz. It includes inherent open-circuit LED protection and is available in thermally enhanced green molding packages. The device is fully RoHS compliant and free from halogens and antimony, making it an environmentally friendly option for engineers.
