PMIC - LED Drivers can be defined as a type of integrated circuit that is designed to drive high-power LEDs at a specified output current, while converting the AC power input into the required DC output. The AP8801SG-13 is a highly efficient step-down LED driver that is capable of providing up to 500mA of adjustable output current. This driver comes with a wide range of features, including over-temperature protection, reverse polarity protection, under-voltage lockout, soft-start, and dimming control support.
The main application field of AP8801SG-13 is LED backlighting, automotive lighting and industrial lighting. It is designed to provide a minimum of 500mA and a maximum of 3A of adjustable output current for lighting applications. The device can also be used for generic high-power DC/DC applications, such as for driving motors, solenoids, and compressors.
The working principle of the AP8801SG-13 is based on a switch-mode DC/DC converter. It uses a DC-DC converter in order to convert the input AC power into the required DC output power. The device is designed to achieve up to 92% efficiency and is capable of operating with a wide input voltage range of 8.5V to 36V. The output voltage is adjustable from 0.8V to 26V, with an output current up to 3A.
The AP8801SG-13 includes two integrated control loops, which are dynamic and static. The dynamic control loop regulates the output voltage, while the static control loop helps maintain stability. The device is able to achieve a very low output voltage ripple, and is capable of withstanding transient inputs in order to maintain continuous LED operation in harsh environments.
The AP8801SG-13 also has built-in protection features, including over-temperature protection and reverse polarity protection. Over-temperature protection prevents the device from overheating, while the reverse polarity protection ensures safe operation even when the power connections are inverted. Additionally, the device comes with a built-in soft-start feature, which modulates the inrush currents of the switched-mode DC/DC converter and helps protect the LEDs from high inrush currents.
The AP8801SG-13 also includes a dimming control support, which allows the user to adjust the output current and dimmer type. The dimmer type can be set to either constant current or constant voltage, depending on the application. Additionally, the adjustable output current allows the user to control the luminance of the LEDs.
The AP8801SG-13 is a highly efficient, step-down LED driver that is specifically designed for LED backlighting, automotive lighting, and industrial lighting applications. It utilizes a switch-mode DC/DC converter to convert the input AC power into the required DC output power, while achieving an efficiency up to 92%. Furthermore, the device comes with a range of protection features, including over-temperature protection, reverse polarity protection, under-voltage lockout, and soft-start. Additionally, the device supports dimming control, allowing the user to adjust the output current and dimmer type.
