The UCD74111RVFT is a high performance, low quiescent current and high efficiency step-down DC-DC switching regulator. This regulator is designed for use in a variety of applications such as automotive, industrial, and consumer products. The UCD74111RVFT offers efficient operation over a wide input voltage range and provides excellent load regulation, fast transient response, and accurate output voltage. It also offers a wide range of adjustable output voltage, allowing the user to select the optimal operating voltage for their application.
The UCD74111RVFT is a synchronous, step-down DC-DC regulator that outputs a regulated voltage from an input voltage source. In a step-down configuration, the input voltage is higher than the output voltage, and in order to maintain the output voltage at a constant level, the regulator must absorb excess energy from the input voltage source. This energy is then dissipated as heat to maintain the output voltage.
The UCD74111RVFT features a pulse-width modulated (PWM) control scheme. This regulates the output voltage by controlling the on and off periods of the switch in the converter. During the switch on period, energy from the input stage is stored in the inductor, and during the off period, this energy is released and then converted to an output voltage. The length of each switch on/off period is determined by the value of the feedback resistors, which results in an output voltage determined by the relationship between the feedback resistors and the input voltage.
The UCD74111RVFT also features an internal error amplifier, which compares the output voltage to a reference voltage and shuts off the switch when the output voltage reaches the set point. This feature, along with the voltage feedback resistors, ensure excellent load regulation, fast transient response, and accurate output voltage, offering the user high performance and reliability.
The UCD74111RVFT is ideal for automotive and industrial applications, such as tests and measurements, audio, central office systems, process control systems, cable television, telecommunications, and networking. This regulator provides designers with a reliable, small size and high efficiency solution, allowing them to optimize their application performance without compromising power supply efficiency.
