Introduction:
RT4803WSC is a DC-DC switching regulator IC that provides highly efficient and precise voltage regulation in portable and power-sensitive applications such as cellular phones and PDAs. This IC includes a buck regulator, a low drop-out (LDO) linear regulator and various protection circuits.
Application Field:
RT4803WSC is a versatile power management IC designed to optimize battery life and increase efficiency in portable applications. It features three synchronous buck regulators, a low drop-out linear regulator, and current-limit & over temperature protection. It is capable of delivering up to 2.4A at 5V, 2A at 3.3V, 1.6A at 2.8V and 1A at 1.2V.
RT4803WSC is the ideal choice for powering up mobile devices and other embedded systems that require multiple voltage rails. It is especially well-suited for high-efficiency battery-powered applications, where its synchronous buck regulators can manage up to 97% efficiency over a wide range of loads.
RT4803WSC also offers a low drop-out, linear regulator (LDR) with up to 95% efficiency over a wide range of load, even at light load. This makes it suitable for powering analog blocks that require a low-noise power supply.
Working principle:
The RT4803WSC is a DC-DC switching regulator with a high level of integration and performance. It is designed to provide a stable, 0.5V to 5V output voltage at currents of up to 2.4A, with the help of a built-in low drop-out (LDO) linear regulator and current-limit protection. The switching regulator operates in a buck configuration, which is more efficient and reduces losses related to voltage conversion.
The RT4803WSC includes three synchronous buck regulators, each with a 0.5V to 5V output voltage range, 0.5A to 2.4A output current and up to 97% efficiency. The output voltage is adjustable and can be programmed by adjusting an external resistor or using the enable pin to switch between two pre-defined output voltages.
In addition, the RT4803WSC also provides a low drop-out linear regulator (LDR) with 95% efficiency over a wide range of load, even at light load. This allows for powering analog blocks that require a low-noise power supply.
The RT4803WSC also features a wide range of protection features, including input under-voltage lockout, over-current protection, over-temperature protection, and over-voltage protection. These features make the RT4803WSC an ideal choice for powering up mobile devices and other embedded systems.
Conclusion:
In short, RT4803WSC is an ideal power management solution for high-efficiency battery-powered applications. It integrates three efficient synchronous buck regulators, a low drop-out linear regulator, and a wide range of protection features. This makes it suitable for powering up mobile devices and other embedded systems that require multiple voltage rails.
