As power management solutions continue to expand into more and more consumer products, the market is ever increasing for new devices to manage this powerful amount of energy. One such device, the RT7247BHGSP, is an advanced energy management solution that offers high performance, efficiency, and small size. This article will discuss the application fields and working principle of the RT7247BHGSP.

The RT7247BHGSP is a DC-DC non-isolated step-down switching regulator designed for integrated power applications. It offers a wide input voltage range of 4.5V to 28V and an output current up to 1.9A. This device is capable of regulating voltages up to 48V and providing high efficiency up to 96%, enabling minimal power losses while converting power efficiently. It can also provide an adjustable output voltage ranging from 0.8V – 7V, giving users the flexibility to customize their power needs.

The RT7247BHGSP is optimized for use in compact, space-constrained applications such as power adapters, battery powered equipment, and other accessories. It is also well suited for use in portable products such as laptop computers, tablets, and wireless chargers. With its low profile and wide input/output ranges, the RT7247BHGSP is a great choice for applications or systems where high power is necessary and wide temperature ranges must be accommodated.

The RT7247BHGSP offers a host of features to help make it an efficient choice for many applications. A PWM/PFM mode selectable buck controller works with the external MOSFETs to regulate the output voltage and reduce power dissipation. It also offers a multitude of protections, including over-voltage, over-current, and over-temperature protection. In addition, the device incorporates a soft-start feature that reduces start-up surge current, improving reliability and mitigating damage caused by any inrush current. Other features, such as cycle-by-cycle current limit and undervoltage lockouts, support safe operation even in extreme conditions.

To take full advantage of the RT7247BHGSP’s features, a few components must be added, including inductors, capacitors, and the associated MOSFETS. A switching frequency of either 200kHz or 300kHz is selectable via a resistor divider. All components are kept small, allowing for a compact and lightweight solution – ideal for space-constrained applications.

The RT7247BHGSP’s control scheme consists of a full-fledged closed loop PWM/PFM buck controller and a floating high-side/low-side driver. In this configuration, the controller senses the output voltage, compares it to the programmed reference voltage and adjusts the switching frequency and duty cycle of the MOSFETs to regulate the output voltage. This ensures that the output voltage remains stable and at the desired level. A PFM/PWM selectable low on-resistance MOSFET driver also helps to minimize power losses during the conversion process.

The RT7247BHGSP is a powerful solution for efficient energy management and offers customers the unique combination of high performance, efficiency, and small size. Its advanced protection and control features make it well suited for a wide variety of applications, making it the perfect choice for powering the next generation of products. Through its tight integration and energy efficiency, the RT7247BHGSP is the perfect power solution for many space-constrained applications.
