The MPQ2908AGF-Z is a member of a family of DC-DC switching controllers specifically designed for computing, communications and consumer applications where high efficiency is required. The MPQ2908AGF-Z provides the user with a high degree of flexibility to configure the device for a variety of different applications. Additionally, the MPQ2908AGF-Z is designed using advanced process technology to achieve high performance and low costs.

The MPQ2908AGF-Z is used as a DC-DC switching controller for mobile computing and consumer products. The device incorporates a dual synchronous gate driver and low on-resistance MOSFETs to support an input voltage range of 1.8V to 5.5V and an output voltage range of 1.2V to 5.0V. The machine can step up and step down, invert the input voltage, and provide adjustable current limit protection. The integrated low-voltage regulations also feature excellent load and line regulation, as well as a startup current of 200mA.

The MPQ2908AGF-Z offers several key features, including built-in pulse-width modulation (PWM) capability, current-limit protection, power save mode, and soft-start circuit. The built-in PWM controller can be configured for either a fixed frequency or an adjustable frequency by using external components and the current-limit protection allows for a wide range of output current values. In addition, the power save mode allows for power savings at light or zero load conditions and the soft-start circuit ensures that the output voltage does not rise too quickly, thereby protecting the system from over-temperature, over-voltage and over-current conditions.

The MPQ2908AGF-Z has an extremely low quiescent current of only 160uA, which makes it well-suited for battery-operated systems. The device also offers a wide 5V operating range and the design of the built-in feedback loop ensures stability of the system over the entire input voltage range.

The MPQ2908AGF-Z is easy to use and provides good performance, enabling designers to quickly and easily implement their system. The device is an ideal choice for applications with strict cost constraints and the device, when combined with its associated E2E modules, provides a solution with an extremely low component count.

In summary, the MPQ2908AGF-Z is a cost-effective DC-DC switching controller. It has a wide input voltage range and a design that allows for flexibility in system configuration. It also offers a low quiescent current, excellent load and line regulation, and adjustable current limit protection. The device is well-suited for battery-operated systems and provides a good solution for applications with tight component and cost constraints.
