AL5809-30S1-7 is a newly developed power management integrated circuit (PMIC), belonging to the LED Driver product family. It is a reliable and cost-effective solution for driving multiple light emitting diodes (LEDs).

The AL5809-30S1-7 performs very efficiently as an LED Driver in a number of different application fields. These include general lighting, street lighting and automotive lighting. This PMIC is designed to meet the lighting requirements in any given application field, such as building lighting, signage, displays, and public utility lighting.

The working principle of AL5809-30S1-7 is a combination of boost and buck principles. The boost principle is used to convert a lower incoming DC voltage into a higher output voltage, while the buck principle is used to reduce an incoming high voltage to a lower voltage. This combination provides the PMIC with the capability to dynamically adjust output current, power and voltage by utilizing a synchronous rectification technique. Furthermore, the PMIC is also able to achieve a very high efficiency, up to 98%, due to its linear topology.

The AL5809-30S1-7 has a wide operating temperature range of -40 C to 85 C and its standby current consumption is as low as 0.75mA. The included Buck-Boost Auto-dimming function also helps to reduce power consumption and extend the lifetime of the LED Driver. The included built-in protection features, such as over-temperature shutdown and reverse current protection, ensure safe usage of the PMIC even in the most demanding operating conditions.

In conclusion, the AL5809-30S1-7 is a reliable and cost-effective PMIC-LED Driver designed to meet the lighting requirements in a variety of application fields. Its boost and buck principles, wide operating temperature range and low standby current consumption make it a reliable device for driving multiple LEDs. The included built-in protection features also ensure safe usage of the device, even in the most demanding operating conditions.
