RT6806ZQV

The RT6806ZQV is a PMIC (Power Management IC) high-performance twin-buck controller which responds to the increasing demand for higher power system efficiency and smarter power solutions. It integrates a synchronous Buck converter and an adaptive Buck converter to control two outputs, offering the highest efficiency and best transient performance for both outputs via dynamic loop response. This makes it ideal for high-current applications, such as notebooks, mobile devices, and telecommunication systems, which require a wide range of power solutions.

The RT6806ZQV is based on a patented Zero Voltage Switch (ZVS) topology, which allows for high efficiency over a wide load range with minimal output voltage droop. Its Zero Overlap Control (ZOC) technology further improves efficiency by eliminating the switching delays that occur when switching from one output to another. Its X-Cap voltage clamps ensure output voltage accuracy by preventing over-voltage conditions from occurring during the switching process.

The RT6806ZQV has several features to meet the demanding requirements of today’s power applications. It incorporates 100% duty cycle operation for Continuously Variable Voltage (CVV) applications, which allows for optimal efficiency at lower loads. It also features a pre-biased softstart, enabling a power-up sequence over a wide voltage range. Combined with its adaptive loop, this prevents any overshoot or undershoot on the output voltage during start-up.

The RT6806ZQV’s advanced adaptive loop architecture simplifies the design and implementation of multiphase power systems. The adaptive loop maintains the desired output voltage accuracy within a ±0.5% range over the full load range and temperature range. This reduces the signal noise and the output voltage ripple in transient conditions, helping system designers save board space by eliminating compensation circuits.

The RT6806ZQV Linear + Switching voltage regulator also offers several safety features such as over-voltage protection and under-voltage lockout. This ensures that the power system remains safe, reliable, and efficient at all times. Furthermore, the RT6806ZQV supports a wide range of power outputs, allowing designers to easily scale the output power and improve the system’s thermal efficiency.

The RT6806ZQV is an ideal solution for a variety of applications requiring high power, high efficiency, and reliability, such as notebooks, mobile devices, and telecommunication systems. By combining several optimally designed power conversion stages into a single IC, it offers a high performance, cost-effective, and space-saving design that meets the rigorous demands of today’s high-power applications.
