AL1676-40DS7-13 is a Primary-Side Regulation (PSR) light emitting diode (LED) driver integrated circuit (IC). It is manufactured by Advanced Linear Devices, Inc. (ALDI) and belongs to their "Smart Power" product line. The AL1676-40DS7-13 has a wide operating temperature range and operates in multiple modes to ensure the most efficient power conversion and management of LEDs.

Application Field

The AL1676-40DS7-13 is a PMIC – LED Driver used for the control of LED lighting systems. It is designed for a wide range of LED configurations, from small and medium sized strings of LED lighting products to large arrays of LED lights. The AL1676-40DS7-13 LED driver is also suitable for applications in both indoor and outdoor LED fixtures. The AL1676-40DS7-13 is a cost-effective way to achieve high efficiency LED lighting while reducing thermal stress and operating temperature.

The AL1676-40DS7-13 is ideal for applications in emergency lighting systems, headlights, spotlights, and other low voltage LED based systems. It is suitable for both traditional and energy saving LED lighting systems. The driver can be used in both commercial and residential buildings. It can also be used in industrial and automotive LED lighting systems.

Working Principle

The AL1676-40DS7-13 is a Primary-Side Regulation driver. This means that, rather than using secondary-side drivers for control, the driver utilizes primary-side regulation techniques, such as linear adjustment of the LED current and pulse-width modulation (PWM) control. In this way, the AL1676-40DS7-13 can be used to provide highly efficient and stable operation, even in the most difficult of applications.

The AL1676-40DS7-13 employs several different methods to adjust the LED current. The driver features a linear current adjustment range of 0-400mA and a peak load current of 1000mA. The AL1676-40DS7-13 also utilizes PWM dimming to control the LED brightness levels. The dimming frequency can be set to 25kHz, 50kHz, or 100kHz and can be further adjusted to provide smooth, flicker free dimming results.

The AL1676-40DS7-13 has an integrated power MOSFET and an undervoltage lockout protection circuit. The power MOSFET helps to reduce heat build up and ensure stable performance. The undervoltage lockout protection prevents damage to the driver and LEDs if the input voltage drops below the preset voltage level. The AL1676-40DS7-13 also features a programmable thermal shutdown, which will shut down the driver and LEDs automatically if the internal temperature rises above a pre-set level.

The AL1676-40DS7-13 also has a thermal protection function. This function provides protection to the driver and LEDs from current and/or temperature overloads. The thermal protection is designed to switch off the driver and LEDs if the internal temperature exceeds the set temperature limit. This helps to ensure safe and reliable operation of the LED system.

The AL1676-40DS7-13 is a versatile and reliable LED driver IC, suitable for a variety of LED lighting applications and environments. Its primary-side regulation technology, wide operating temperature range and robust protection functions make it suitable for some of the most demanding LED lighting applications.
