LEDs are a commonly used light source for various applications, ranging from consumer electronics, such as cell phones and laptops, to industrial applications, such as automotive headlights and automotive interior lighting. As the demand for LEDs continues to grow, the need for efficient and cost-effective LED drivers also increases. AL8807BMP-13 is a high-efficiency, low-cost LED drivers with integrated Functions. It can be used to drive multiple or single LEDs at up to 250mA of current output and is widely used in the PMIC-LED driver industry.

AL8807BMP-13 is equipped with several important features. It uses a 9V-18V input voltage with a maximum switching frequency of 1MHz and can output up to 250mA of current. The chip also supports an adjustable open/close loop system, allowing control of LED brightness, as well as operate in various modes, including pulse width modulation (PWM), pulse frequency modulation (PFM), and automatic pulse frequency dimming (APF). In addition, AL8807BMP-13 also has a built-in protection circuit, which is used to limit the output current and protect the LEDs from catastrophic failure.

In terms of the working principle of AL8807BMP-13, it is based on a PWM closed loop technique that uses cycle-by-cycle current sensing to adjust the duty cycle of the LED gate voltage. The LED current is adjusted by varying the duty cycle of the LED gate voltage to reach the required output current. The duty cycle is adjusted as a function of the load current and the reference voltage of the output control loop. The duty cycle is further smoothed by introducing a high-frequency ripple capacitor across the output limiting resistor.

When it comes to application fields, AL8807BMP-13 is widely used in outdoor lighting such as garden lighting and street lamps. It can also be used for a variety of indoor lighting such as ceiling lights, down lights, wall sconces, and desk lamps. Due to its wide-range input voltage, high-efficiency, and low cost, it is widely used in automotive interior and exterior lighting, such as brake lights, taillights, and headlights. Additionally, AL8807BMP-13 is suitable for a variety of consumer electronics, such as mobile phones, laptops, and LCD displays.

In conclusion, AL8807BMP-13 is a high-efficiency, low-cost LED driver with integrated Functions. It is widely used in the PMIC-LED driver industry, and is used to drive multiple or single LEDs at up to 250mA of current output. It can be used in a variety of applications, from outdoor lighting to automotive interior and exterior lighting and consumer electronics.
