Introduction of TPS92513HVDGQR

TPS92513HVDGQR is an advanced, high-efficiency, low-power dimmable LED control and power system-on-a-chip (SoC) device that can be used in general lighting applications. The device has an integrated power supply, LED current regulator, and a MCU interface. The wide operating temperature range of -40 to 85℃ ensures a robust application in various lighting environments.

Application Field

TPS92513HVDGQR was designed to provide high-efficiency LED control in street lights, downlights, and other related LED lighting applications. It provides the LED power system with LED dimming, over-voltage, and over-current protection. Compared with traditional lighting drivers, it offers more efficient operation, high power factor, fast transient response, and reduced component count.

The TPS92513HVDGQR also offers communication interface options such as UART, SPI and I2C. It can also be used with wireless control systems such as Wi-Fi, Bluetooth, and Zigbee. Its integrated design makes it ideal for applications that require quick installation or efficient operation in difficult environments.

Work Principle

The TPS92513HVDGQR employs pulse-width modulation (PWM) dimming technology on its output stage to efficiently control the current level of the LEDs. Its integrated control loop also allows users to set precise current levels for LEDs with precise control. Additionally, it can also operate with an adjustable frequency range from 3kHz to 100kHz. This allows for flexibility in the application, allowing for different dimming levels and flicker free operation.

The device works in the following steps: The MCU sends a signal to the TPS92513HVDGQR, containing the desired current level and dimming level. The TPS92513HVDGQR then processes the signal and configures the necessary parameters before generating the control pulses. The device then produces the pulse-width modulation (PWM) signal, which is then used to control the current level of the LEDs. Finally, the device is connected to the external rectifier and the LEDs, and the LEDs are driven accordingly.

Conclusion

The TPS92513HVDGQR is a high-efficiency LED driver designed for LED lighting applications. It offers several features such as LED dimming, over-voltage, and over-current protection, as well as communication interfaces for wireless control. Its pulse-width modulation (PWM) dimming technology provides precise control over LED current levels, and its wide operating temperature range of -40 to 85℃ makes it suitable for various lighting environments.
