The RT2701GQW is a Dual-Phase Synchronous Buck Controller with Integrated Dual Digital Power-Control Processors, and it is a key component in the PMIC Voltage Regulators DC DC Switching Controllers field. The RT2701GQW can be used in a variety of applications, such as memory and computing, game consoles, set-top boxes, network communications equipment, automotive, and other consumer electronics.

The RT2701GQW provides a pair of integrated digital PWM controllers in a single chip, which can be used together or separately to provide flexible power solutions. The synchronous buck is ideal for high-voltage point-of-load applications such as core, memory and peripheral power supplies. The fully integrated solution reduces external component count and board area, eliminating the need for external clock generation.

The RT2701GQW integrates two operating regions: \'Active-Mode\' and \'Q-Mode\'. Active-Mode enables the adjustment of current and power levels with a single external resistor plus a single digital register. In Q-Mode, the voltage and current are adjusted through a single digital register.

The RT2701GQW features an advanced PMBustm module, which supports a range of PWM functions, including power measurement, frequency programming, and output voltage setting. The chip also supports dynamic frequency control to reduce noise and minimize EMI. In addition, the chip is capable of controlling multiple rails and Multiple Output Voltage (MOV) implementations.

The RT2701GQW uses Pulse-width Modulation (PWM) to regulate output voltage. PWM works by switching on and off current to the load at a predetermined frequency. The duty cycle of the switching determines the average voltage applied to the load. The RT2701GQW utilizes a high-precision digital feedback loop to maintain a tightly regulated output voltage. The loop can be adjusted to ensure that the output voltage is always within a specified range.

The RT2701GQW also offers a unique Reduce-Voltage Sense feature, which allows users to monitor the output voltage without an external sense resistor. This eliminates the need to place resistors and other components on the application’s PC board and simplifies the design process. The Reduce-Voltage Sense feature also helps improve reliability by reducing the risk of component failures due to joule heating.

The RT2701GQW supports a variety of power states, including power-down and power-on. The chip also supports a range of Application Programmable Interface (API) signals to enable easy integration within existing application software. Finally, the RT2701GQW is designed to meet safety requirements and is RoHS compliant.

The RT2701GQW is a powerful and versatile PMIC Voltage Regulator DC/DC Switching Controller. It provides integrated digital PWM controllers and advanced PMBusTM functions for controlling multiple rails. The Reduce-Voltage Sense feature helps reduce component count and simplify circuit design and the chip is RoHS compliant and meets a range of certification standards.
