PMIC (Power Management Integrated Circuit) is a device that integrates multiple functions and integrates the functions of power circuits and analog circuits into one IC. LED driver is a kind of Centralized Power or LED lighting products, which are growing in popularity due to their multiple advantages such as compact energy saving and long service life. Among the LED driving ICs, MAX16836ASE+ is an excellent solution.
MAX16836ASE+ Application Field
MAX16836ASE+ is designed for manual dimming of industrial white LEDs and multiplexed LED applications. It is an integrated 3-channel constant current LED driver for industrial white lighting applications. MAX16836ASE+ has a built-in power factor correction (PFC) and output current regulation, and a range of features. It can provide a constant current of 30mA to 1000mA, and a power range of up to 36V. The internal PFC takes over a wide range of input voltages, so the output current stays constant. The output current can be easily configured using a low-cost external sense resistor. The MAX16836ASE+ can be used in a variety of applications, including display backlighting, LCD TV lighting and industrial white lighting.
MAX16836ASE+ Working Principle
The MAX16836ASE+ LED drivers are designed for manual with higher efficiency and dimming control of LED lighting systems. Its working principle is to use two resistors to adjust the output current,which is provided from the company\'s website. The brightness of the LED can be adjusted by adjusting the resistance to the oxygen, so as to realize the dimming of the LED. The voltage drop of the two resistors is superposed to form a voltage signal that is proportional to the output current of the LED, which is sent to the dimming pin of the LED driver chip to be read by the LED driver. The LED driver adjusts the mismatch of the LED string to ensure its current output uniformity. The circuit process is as follows:
- Dimming Control: The dimmer signal is sent to the dimming pin of the LED driver so that it can detect the setting voltage. The voltage is transmitted to a digital-to-analog converter, which then adjusts the setting current of the dimming control.
- Current Regulation: The output current of the MAX16836ASE+ is set by a current amplifier with a feedback resistor. This is usually done through a sense resistor on the output of the device.
- Visually Irregular Protection: MAX16836ASE+ also has a built-in mismatch protection for each channel. The protection measures the forward voltage drop at each LED. If the current of a single LED exceeds the preset allowed range, the driver automatically adjusts the current to the level.
Conclusion
MAX16836ASE+ is a highly integrated multi-channel LED driver. It can provide constant current from 30mA to 1000mA and power range up to 36V. It also has excellent features such as built-in power factor correction, output current regulation and visual mismatch protection. These features make it an ideal solution for a variety of manual dimming applications, including LCD TV lighting and industrial white lighting. The MAX16836ASE+ is an excellent choice for users who need a robust and reliable LED driver.
