REG71055DDCT is an advanced two-channel, high-efficiency switching voltage regulator designed for applications where reliable, low-noise, and low-omission power regulation are needed. The device implements a precise, low-noise PMOS buck converter topology, with each channel designed to operate either independently or in a synchronous configuration. It also provides an additional supply voltage regulation loop in order to maintain an efficient and stable power supply over a wide input voltage range.This high-efficiency two-channel switching regulator is a highly integrated power supply control solution offering enhanced system flexibility and efficiency. The device is also equipped with a wide range of protection features, including overvoltage protection and thermal shutdown, as well as adjustable soft-start and over-temperature protection circuits. It is also optimized for use in low EMI environments thanks to its low-noise power converter design. A wide input voltage range, high switching frequency and built-in power limiting are also features that may be beneficial in many applications.One of the unique features of the REG71055DDCT is its self-diagnosis function. Using sensing circuitry, the device continuously monitors its own temperature, input voltage and output current, allowing it to provide immediate operational feedback. Furthermore, it allows the user to program a power limit, as well as assign a power-good signal that can be used to detect a fault condition.In applications where precision power regulation is required, the REG71055DDCT can provide up to 0.8V output voltage accuracy and a wide output voltage range of 0.6V to 5.5V. The device can provide up to 3A of output current, making it suitable for use in a wide variety of applications such as wide temperature range DC-DC converters, baseband power management components, power amplifier modules, and PDAs. Additionally, the device is suitable for use as a high-efficiency power supply for low power LED lighting.The REG71055DDCT is powered by a switched mode power supply consisting of an inductor and two transistors. In order to ensure efficient operation, the device employs a synchronous buck topology to regulate the output voltage. The inductor and the switch transistors control the power flow, ensuring that the output voltage remains constant. The synchronous architecture also helps to regulate and filter out noise, eliminating the need for external low-pass filters. The switching FETs are controlled by a PWM currentmode algorithm, which allows the device to accurately regulate the output voltage even under heavy load conditions. In addition, the switched mode power supply also reduces power consumption and thus contributes to greater system efficiency.The REG71055DDCT delivers an efficiency of up to 94%, as well as having low operating temperature and low-noise operation, making it an ideal choice for a wide variety of power management applications. It is also designed to be reliable and easy to use, allowing customers to minimize their time to market and reduce overall system costs.
