The MSLB9082DHB LED driver is an evaluation board from Microchip\'s LED Lighting Design Center category, specifically in its LED drivers category. This board is used for a wide variety of applications and is provided in both a consumer and commercial grade of LED drivers, giving engineers and designers the flexibility to choose the one that best suits their needs. The MSLB9082DHB provides the capability to provide essential thermal management and high precision illumination, making it the ideal choice for a range of applications.In terms of its application field, the MSLB9082DHB is especially useful for indoor lighting. It can be used to drive LED light sources with power up to 200W at 12-24 V DC. It operates at a frequency of 400 kHz and is designed to have a PWM dimming capability. The MSLB9082DHB is suitable for a variety of LED-based lighting applications such as: indoor lighting, cove lighting, decorative lighting, wall washers, accent lighting, spotlights, etc.As for its working principle, the two boards that make up the MSLB9082DHB LED driver—the Power board and the Dimmer board—operate in tandem to provide optimal performance. The Power board provides the necessary power for the LEDs, and the Dimmer board enables the precise modulation of the LEDs’ current and brightness.The Power board comprises of a power train that consists of a Synchronous Rectifiers (SRs) Buck converter, two Linears Regulators (Ls), and two current regulators to control the light intensity and spread of the light emissions. The Power board also houses an Integrated Voltage Regulator (IVR) and Adaptive and On-Demand Control (AODC) to ensure precise thermal management and high precision illumination.The Dimmer board is the control board of the LED driver, which houses the LED dimmer and a three-channel Pulse Width Modulation (PWM) block to manage the light intensity and spread of the light emissions. Using this board the user can change the light intensity from 0% to 100%. It also allows for the user to control the light distribution, making it ideal for a range of lighting applications.The working mechanism of the MSLB9082DHB LED driver is simple: when a voltage is applied, it will activate a power train, consisting of a Synchronous Rectifier Buck converter, two Linear Regulators, and two current regulators, which will then set the desired intensity and spread of the LEDs’ light emissions. This is achieved by selectively turning on and off certain LEDs, resulting in the desired dimming effect.The MSLB9082DHB LED driver is the ideal choice for a wide variety of lighting applications requiring high precision illumination and thermal management. Its two-board design allows for the user to customize the light intensity and spread of the LEDs’ light emissions, making it the perfect solution for any lighting application.For more information about the board, as well as detailed documentation and installation instructions, please visit the Microchip website.
