The RT9728ALZQW is an integrated circuit from the Power Management IC (PMIC - Power Distribution Switches, Load Drivers) family. It is a high voltage, low dropout (LDO) voltage regulator designed for Power over Ethernet (PoE) applications. The device provides precision output voltage accuracy, which makes it suitable for various PoE applications. It also features excellent line and load regulation, as well as transient response.The typical application field of the RT9728ALZQW is Power over Ethernet. This device is designed to provide an ultra-low output voltage ripple and low noise when operated at a nominal 15V input voltage. The on-chip integrated reverse current and thermal shut-down protection features, as well as the optimized energy saving mode, make this device an ideal choice for a variety of Ethernet-based applications.The working principle of the RT9728ALZQW is based on the principle of voltage regulation. Its regulation is enabled by its internal control loop, which compares the output voltage to the voltage reference provided by the internal temperature compensated band gap reference. When the internal control loop detects a deviation in the output voltage from the pre-set level, it switches off the external output transistor to reduce the voltage to the desired level.In addition to providing voltage regulation, the RT9728ALZQW also offers protection against overload or short circuit conditions. The device is equipped with a low-side current limit circuit, which shuts down the power supply in case of an over-current and automatically resumes the operation after the over-current is cleared. The chip also features a thermal protection circuit, which limits the heat generated by the internal regulator and reduces the risk of circuit damage due to overheating.The RT9728ALZQW also provides reverse polarity protection, which prevents voltage spikes from being fed back to the system board. This feature is particularly useful for applications, where the power supply may be reversed due to external factors, or when the connector has been plugged in with the incorrect polarity. Furthermore, the chip has a protection circuit for VBUS over-voltage, which ensures the safety of the connected devices.In summary, the RT9728ALZQW is an integrated circuit from the PMIC - Power Distribution Switches, Load Drivers family. The device is designed for Power over Ethernet (PoE) applications and provides precision output voltage accuracy. Its working principle is based on the principle of voltage regulation, where its internal control loop compares the output voltage to the voltage reference and automatically adjusts the output voltage to the desired level. It also features several protection features, such as current limit, thermal protection and reverse-polarity protection, as well as protection against surge and over-voltage.
