RT7273GQW is one of the newest additions to the family of DC DC Switching Regulators offered by Richtek Technology Corporation. This device is specifically designed for the PFC (Power Factor Correction) and LLC (Low Light Control) applications in power conversion solutions.

The RT7273GQW is a high efficiency DC-DC converter with over 90% efficiency and is able to work with an input voltage range of 6.5V to 18V. It conveniently provides multiple outputs, with an adjustable output voltage range of 0.6V to 5.5V. The RT7273GQW also works with a maximum output current of 1.3A, making it well suited for applications such as LED lighting, LED backlighting and POE (Power over Ethernet) applications.

The product is designed for applications where high efficiency and low cost are desired. The RT7273GQW also features a programmable switching frequency from 500kHz to 2MHz, allowing the user to tailor the operating frequency to their application. With the patented Zero Grade current sensing scheme, the RT7273GQW aims to maximize system efficiency and minimize component count. This makes the RT7273GQW ideal for small form factor designs such as tablet PCs and smartphones.

The RT7273GQW features an advanced power management architecture that is designed to maximize the efficiency and minimize component count while providing small form factor designs. The device also features a configurable peak current limit feature which is useful to reduce the output power when the current is above the pre-defined threshold. This feature is especially useful in applications where the output voltage is not fixed.

The RT7273GQW provides excellent transient response, enabling the device to support multiple output combinations such as single output, dual output, and high current outputs. With its current sense amplifier the RT7273GQW significantly reduces the output ripple, allowing the device to support very low noise solutions. The device is also optimized for low-EMI solutions.

In summary, the RT7273GQW from Richtek Technology Corporation is a high efficiency DC-DC converter designed for PFC and LLC applications, featuring a 6.5V to 18V input voltage range, adjustable output voltage range of 0.6V to 5.5V, maximum output current of 1.3A and configurable peak current limit. With its advanced power management architecture, the RT7273GQW is ideal for small form factor designs such as tablet PCs and smartphones. The RT7273GQW also enables a wide array of configurations such as single output, dual output and high current outputs, as well as low-EMI solutions.
