TPS54824RNVR Application Field and Working Principle

Regarding new generation power management integrated circuit (PMIC) technology, the introduction of DC-DC switching regulators such as TPS54824RNVR has brought tremendous improvement in power efficiency for modern equipment. In this article, we will discuss the application field and working principle of TPS54824RNVR.

The TPS54824RNVR voltage regulator, a new member of the high efficiency Texas Instruments DC-DC switching voltage regulator family released in November 2019, is mainly used to convert a wide input voltage range into a completely regulated output voltage without the need of additional switching components. Its wide input voltage range covers the most popular 5V, 12V, and 20V input voltages, allowing it to be used in a wide variety of places. The maximum input voltage of the regulator is 28V, making it ideal for low voltage applications in industrial or automotive control systems or fast-charging systems. The versatility of this device also makes it suitable for use in battery charging or portable USB devices.

In terms of applications, the TPS54824RNVR voltage regulator is mainly used in battery charger, notebook PC power supply, service station systems, and various DCDC converter applications. Its wide input voltage range covers 5V, 12V, and 20V input voltages, allowing it to be used in DC-DC converters in automotive and industrial control systems, LCD monitors and displays, fast-charging systems, solar inverters, compressors, and other products.

The TPS54824RNVR voltage regulator features a static efficiency of up to 97.5%. It has various adjustable frequency (250kHz-2.2MHz) and peak current levels. With respect to output current capability, the maximum continuous current is 7.5A. The switching voltage regulator also incorporates a cycle-by-cycle current limit protection as well as thermal protection, further enhancing its safety and reliability.

The working principle of the TPS54824RNVR voltage regulator is quite simple. Upon receiving the input voltage, a power MOSFET switch is activated, which in turn activates the synchronous rectification. The voltage is then rectified and smoothed to produce a regulated output voltage, which is then sent to the load. When the load is disconnected, the power MOSFET switch is shut down and the regulator enters an idle state. This cycle is repeated as long as the input voltage is present, allowing the device to continuously provide a regulated output voltage regardless of the input voltage.

In conclusion, the TPS54824RNVR voltage regulator is a valuable addition to Texas Instruments’ DC-DC switching voltage regulators family. This efficient device can be used in a wide variety of applications, making it an ideal choice for low voltage applications in industrial or automotive control systems, battery charging, or fast-charging systems. Its static efficiency, wide input voltage range, adjustable frequency and peak current levels, as well as its cycle-by-cycle current limit protection and thermal protection, give it unmatched versatility and reliability.
