RT9085AWSC

The RT9085AWSC is a synchronous step-down, DC-DC switching regulator IC designed for battery-powered and power supply applications. It is a highly efficient and compact solution that provides an adjustable output voltage ranging from 0.8V to 5V. It has an integrated MOSFET with a maximum output current of 3A.

The device is designed to optimize power efficiency, reduce power loss, and improve EMC performance. It provides a 0.6V reference voltage, adjustable soft-start, and adjustable frequency. It also incorporates various protection features such as over-current protection (OCP), over-temperature protection (OTP), under-voltage lockout (UVLO), and an adjustable restart timer. The device is available in an USO 8-pin package.

The RT9085AWSC is capable of operating at a switching frequency of up to 2.2MHz, allowing designers to select the optimal frequency for their application. It also features an adjustable soft-start to limit large inrush current that occurs at start-up, providing a reliable turn-on time and stable output voltage without large instantaneous power demand. The output voltage can be adjusted via an external resistor divider. Besides, the over-current protection can provide protection for the circuit and ensure the system operates within a safe power range.

The RT9085AWSC is ideal for applications such as notebook computers, tablets, smartphones, and other portable devices. It is designed to provide a very efficient, adjustable, and stable power supply solution as well as reduce power consumption and improve EMI performance. Furthermore, it is a low-profile solution that is easy to design into virtually any platform supporting 3A output current.

The RT9085AWSC DC-DC switching regulator is suitable for applications with voltage levels ranging from 0.8V to 5V. It uses a synchronous rectification circuit to step down the input voltage to a lower output voltage, providing excellent regulation and transient response with low output voltage ripple. The MOSFET is integrated into the device, thereby reducing the overall solution size and power loss in the system. The switch FET also provides short-circuit and over-current protection as well as adherence to EMI standards.

The RT9085AWSC can be used in various applications where a voltage regulator is needed. Its high efficiency and low power loss make it suitable for battery-powered applications, such as notebook computers, tablets, smartphones, and other portable devices. It is also suitable for DC-DC applications including DC-DC converters and DC power supplies. This device is also suitable for motor control applications using a boost-converter circuit.
