TPS92691EVM-752 is a general purpose evaluation board for TPS92691, which is a highly integrated, high-efficiency LED driver solution for indoor Luminaire applications, designed for driving LED strings with constant current.
Introduction
The TPS92691EVM-752 evaluation module is a signal-controlled, constant-current LED driver designed to provide high efficiency and small size, while providing an easy and cost effective platform for evaluation and testing. The TPS92691EVEM-752 includes a variety of features such as, highly integrated current sinks with integrated dimming, adaptive dimming, wide-range input voltage and high-efficiency standby. This drive has a wide range of applications, suitable for applications without rectifiers such as panel lights, spotlights, ceiling lamps, and other indoor luminaires.
Features
The TPS92691EVM-752 is a highly integrated solution that includes the following features:
- Highly integrated current sinks with integrated dimming: The integrated dimming mechanism allows for up to 5 dimming modes, whereas adaptive dimming is adjustable by an external resistor.
- Wide-range input voltage: The DC input voltage range is 9V – 30V maximum and 7V minimum.
- High efficiency standby: The standby power consumption is static, and is not affected by the output current. It also provides high efficiency in standby mode.
- Signal-controlled dimming: The dimming status is monitored and controlled by a signal from the system.
- Protection: The board is designed with common over current, overvoltage and temperature protection, which allows for no additional protection circuit for the driver.
Applications
The TPS92691EVM-752 LED driver can be used in a variety of applications including panel lights, spotlights, ceiling lamps, and other indoor luminaires. It is optimized for driving LED strings of up to 13.8W, with up to 30V DC input voltage, and can be adjusted to meet the various application requirements. Additionally, a dimming feature is present, which can be used to adjust the light intensity based on the user’s preference.
Working Principle
The TPS92691EVM-752 works by controlling the current flows in the LEDs. The driver regulates the current in the LEDs by controlling the on-time and off-time of the LEDs. To adjust the intensity of the LEDs, a digital signal is provided to the driver to control the on and off time of the LEDs. The on-time of the LEDs is managed by a P55 controller with an external control signal, while the off-time is managed by the MCU. The driver continuously monitors the output current, the temperature of the LEDs and other parameters to ensure the desired performance is maintained. Additionally, the driver can be adjusted for different applications by changing the values of resistors and capacitors.
Conclusion
The TPS92691EVM-752 is a high efficiency LED driver designed for indoor Luminaire applications. It includes a wide range of features such as integrated dimming, wide-range input voltage, high efficiency standby and signal-controlled dimming. Additionally, the board is designed with various protection features, which allows for easy and cost effective evaluation and testing. The TPS92691EVM-752 can be used in a variety of applications, such as panel lights, spotlights, and ceiling lamps.
