RT9715BGF belongs to the PMIC – Power Distribution Switches, Load Drivers category. It is a uniform-current-controlled, high-side and low-side single synchronous Buck switching regulator for the adjustable low voltage. The device features a fully synchronous rectification scheme and is able to connect multiple channels of output regulators to form a multi-phase solution.

For improved system performance, RT9715BGF also incorporates various integrated protection functions such as Over Current Protection (OCP), Over Voltage Protection (OVP) and Under Voltage Protection (UVP). In addition, a unique current balance technique is applied to balance the load current among different phases. RT9715BGF also has a built-in Fast Transient Response (FTR) function, allowing it to respond quickly to abrupt load changes without compromising the system output accuracy.

The RT9715BGF is designed for use in applications such as industrial, consumer, computer & peripheral and automotive. It provides up to 1A current-limited output with a wide input voltage range of 2.92V to 16V, an adjustable output voltage of 0.9V to 5V, and a reasonable external component count. In addition, the device offers low quiescent current for improved efficiency and high efficiency operation with remarkable switching frequency of 1.2MHz to minimize size of components.

With the combination of the advantages from RT9715BGF’s architecture and the protection/balance functions, the device helps designers to achieve clean and efficient power supply in modern power management applications.

RT9715BGF employs a unique working principle which consists of three major parts: the synchronization and regulation loop, the control loop and the protection loop. In the synchronization and regulation loop, the device can detect the phase current and the output voltage through the current sensing circuit and voltage sensing circuit. The phase current is then compared against the output voltage to make sure that the voltage can be regulated accurately within the required range.

In the control loop, the RT9715BGF is designed to generate a uniform current flow throughout its output channels. This is accomplished by connecting each switching node to a comparator, which ensures that the current in each switch is always the same as the other switches. In order to prevent the output voltage from dropping during transients or sudden load changes, the device also features a fast response time and a parasitic current ramp-up feature.

Lastly, the protection loop offers OCP, OVP, and UVP protection for the RT9715BGF. These protection features will activate if any of the three criteria mentioned earlier are exceeded. In addition, RT9715BGF also has an over temperature protection state which shuts down the device in the event of sustained over temperature.

It is apparent that RT9715BGF is highly capable of resolving a wide range of applications. Its power-management solutions provide robust and reliable performance while allowing designers to optimize their power supply solutions to improve their product efficiency.
