The ZNBG5116Q24TC is a general-purpose, low-leakage, high-efficiency modular power supply integrated circuit (IC). It is a PMIC (Power Management IC) from Texas Instruments that provides specialized power supply solutions for high-end applications. It is a two-phase switching regulator consisting of high-voltage input, low-voltage output, and a fan controller with optional temperature sensors.

Application Field

The ZNBG5116Q24TC is designed for use in audio, video, and gaming applications, where the need for accurate power is critical. It is ideal for powering high-performance gaming rigs, as well as low-power home theater systems. It can handle up to 50 W of power. It is commonly used in consumer electronics such as TVs, monitors, and gaming consoles.

Working Principle

The ZNBG5116Q24TC consists of two basic parts: a power supply and a fan controller. It operates in two distinct phases: first, the power supply section provides a source of regulated power to the device it is connected to, and then the fan controller engages to regulate the temperature of the device. The fan controller works by monitoring the temperature of the device and activating an appropriate fan speed to maintain its optimal temperature.

The power supply section of the ZNBG5116Q24TC consists of an AC-DC converter which converts the input AC line voltage into a low-voltage DC output. This DC output is then regulated by a voltage regulator stage to provide a constant, predictable power supply for the device it is connected to. It can support both a positive and negative voltage output. It also includes an over-current and over-voltage protection circuit, which helps ensure no damage is done to the device in case of a power surge or overload.

The fan controller of the ZNBG5116Q24TC utilizes temperature sensors to sense the temperature of the device. Depending on the temperature of the device, it will then adjust the fan speed accordingly. This ensures that the device is always performing at the optimal temperature, which ensures long-term stability and reliability.

The ZNBG5116Q24TC is also designed with a low-current standby and low-power idle mode. This helps to conserve power and reduce energy costs, while still allowing the device to be operational when needed.

Conclusion

The ZNBG5116Q24TC is a specialized power management IC designed to provide reliable and efficient power solutions for high-end audio, video and gaming applications. It is a two-phase switching regulator, consisting of a high-voltage input, low-voltage output, and fan controller with temperature sensors. It is capable of providing up to 50W of power, and has over-current and over-voltage protection, as well as a low-power standby and idle modes for optimized energy efficiency. The ZNBG5116Q24TC is a great choice for powering high-performance gaming rigs and home theater systems.
