PMIC, or Power Management Integrated Circuit, refers to devices primarily used to produce, measure, and control electrical power. LED drivers fall into the category of PMIC and they primarily process electricity to control individual light emitting diodes (LEDs). To do this, LED drivers use a variety of different components, including LED drivers like the TCA62723FMG.The TCA62723FMG is a 3A, Configuration Mode LED driver. This allows the output (load current) of the driver to be programmed and allows the flexibility to be adjustable and optimized to suit a variety of applications. As the roles of LEDs expand and the needs increase, manufacturers can now address the requirements of many applications through this driver.The primary function of the TCA62723FMG is to control the brightness and current supplied to each LED. The Programmable Soft Start (PSS) feature also allows for smooth and gradual turn-on of the LED string. Through its MakeQ program, this driver can store different programs to be called up when needed. This ensures that, when the driver is turned on and the default settings take effect, it can quickly run the program that is already preloaded and stored. The EL application field of the TCA62723FMG can be divided in two categories, direct current (DC) and alternating current (AC). For DC applications, the TCA62723FMG can be used to control a range of LED lamps, such as automotive headlights and backlights, streetlights, and spotlights. This driver can also be used for indoor lighting applications, such as LED downlights, LED ceiling lights, LED panels, LED strip lights, LED light bulbs, LED modules, LED displays, and LED flood lights.In AC applications, the TCA627237FMG can be used for applications such as LED wall washers, RGB lighting, RGB controllers, RGB wall washers, and RGB strips. Additionally, with its adjustable intensity and dimming features, this device can be used in lighting and display applications, such as cinemas, exhibitions, digital cinema, indoor lighting, outdoor lighting and hospitality lighting.The working principle of the TCA62723FMG is simple and intuitive. The input voltage is first converted to the desired output voltage by the on-chip DC/DC converter. This output voltage is then applied to the LED string. The LED string is then switched on and the current flow is regulated by the on-chip current regulator, which is programmed to suit the application. The current regulation is done using the PWM inputs of the TCA62723FMG. This enables the driver to adjust the current according to the changing conditions and ambient light levels. Additionally, this driver also supports pulse width modulation (PWM), dimming and PWM dimming control. This ensures that the entire LED string can be dimmed uniformly without any illumination spots or constant flickers.In conclusion, the TCA62723FMG from Texas Instruments is a powerful and versatile LED driver that can provide uniform lighting for a variety of applications in both DC and AC current fields. This driver is programmed easily and enables uniform illumination with adjustable current and PWM control. The PSS enablement also provides faster turn-on times, allowing the driver to quickly deliver the desired brightness and performance.
