The RT8010-10GQW is a DC-DC step-down current mode switching regulator specifically designed for powering high current digital loads. It features high efficiency, fast transient response, high current and low EMI noise, making it suitable for applications that require high switching frequencies. Its wide operating supply voltage range (4.5V to 24V) allows robust operation over a wide range of input voltages, and its high-impedance feed-forward control loop allows for low output voltage ripple and highly accurate regulation. The device is integrated with over-temperature protection, under-voltage lockout and cycle by cycle current limit protection.

The RT8010-10GQW is available in a surface mount 16-pin SSOP package and is suitable for applications including powered video cards, notebook PCs, audio systems, data acquisition systems, automotive and industrial motor control, renewable energy systems, server systems, and high-end lighting applications.

The RT8010-10GQW provides pin-selectable pre-bias startup and output voltage tracking options, allowing designers to tailor converter performance to an application. The pre-bias startup mode enables startup into a pre-biased output stage, allowing for faster and smoother startup times compared to traditional startup methods, and the output voltage tracking option allows for the output voltage to track an internally or externally generated reference voltage for applications that require an adjustable reference voltage output.

The RT8010-10GQW operates in current mode, allowing a tight loop control between input voltage and output voltage, without the requirement of an external loop compensation network. It also uses a hysteretic control loop to maintain the switching frequency over a wide range of load conditions, guaranteeing fast transient response and minimum output voltage ripple. By controlling the peak switch current and duty cycle via an external resistor, the output voltage can be easily adjusted.

The RT8010-10GQW is an ideal choice for designers of high-efficiency, low-EMI converter applications, delivering the highest performance and accuracy in a wide variety of applications, including switched-mode power supplies, DC/DC converters, servers, PC power supplies, and portable equipment.
