The TPS92512HVDGQR is an LED driver controller module, belonging to the Power Management Interface Controller (PMIC) category and specifically referred to as an LED Driver. An LED driver takes an input voltage, and using the TPS92512HVDGQR integrated circuit, regulates the voltage output to power and control Light Emitting Diode (LED) systems. LED drivers help maximize the efficiency of the LEDs themselves, maintain brightness levels and prolong the life of LEDs.

The TPS92512HVDGQR is a programmable, current-mode boost and buck-boost LED driver with an integrated high-side switch and a dedicated enable input. This integrated driver is suitable for driving LEDs with an output voltage up to +36V and a maximum output current of 1A. The output can be controlled with a linear, PWM, or analog dimming signal, allowing either manual or digital dimming control of the LED brightnes. This driver is available in a 6-pin PowerSSO package, making it a compact and easy to integrate solution for lighting control systems.

The TPS92512HVDGQR device is designed to provide the correct output voltage and current to power LEDs from existing battery sources. The operating voltage range is from 2V to 18V, allowing battery-driven solutions to be powered by several commonly available power sources including alkaline, Li ion, or LiPo. This device features two separate input terminals allowing it to be utilized in a buck-boost or a boost-only configuration. This provides flexibility to the designer to accommodate different output voltage requirements between given applications.

The TPS92512HVDGQR is highly configurable, allowing designers to program the LED driver to best suit the specific LED requirements. This device features an internal slope compensation network that allows optimally adjust the output current to match the LED’s characteristics. The device has several protection features to ensure safe operation. It has programmable over-temperature protection, over-current protection, under-voltage lockout protection, and restart time delay.

The TPS92512HVDGQR is a versatile LED driver controller module that can be used in a number of applications. The integrated high-side switch and dedicated enable input provide a small and efficient way to control an LED lighting configuration. The large range of input voltage possibilities and ability to adjust the output current through programming makes the TPS92512HVDGQR well suited for several common LED applications. These include LED signs, decorative lighting, and variable lighting installation systems.

In summary, the TPS92512HVDGQR is a well written, highly versatile LED driver whose working principle is to take an input voltage, and using the TPS92512HVDGQR integrated circuit, regulate the voltage output to power and control Light Emitting Diode (LED) systems. The integrated high-side switch and dedicated enable input allow efficient control of the LED system. Also, its configurability allows designers to program the device to best suit their needs. Therefore, the TPS92512HVDGQR is suitable for a wide range of LED applications.
