The MP2162AGQHT-Z is a completely integrated DC DC switching regulator designed for handheld applications. It contains a low power P-channel MOSFET, an internal ripple buffer and current-mode control for fast transient response. The highly integrated design features required to build an efficient and cost-effective power supply make it suitable for multiple applications including cellular phones, mobile data terminals and other handheld devices.

The MP2162AGQHT-Z is a part of a family of monolithic integrated switching regulators available in 4.5 V to 28 V input voltage and 3.3 V to 14 V output voltage versions. It has multiple control and protection features, allowing for complete turn-key regulator designs. It provides over current protection and over temperature protection, which make it a reliable and safe choice for many types of powering applications. It has a high power efficiency of up to 86% and offers a wide selection of inductors from industry-leading vendors.

The MP2162AGQHT-Z features adaptive on-time control with active voltage positioning (AVP) circuitry. This allows for load line regulation in the output voltage without need for complexity and external components. It also features a built-in branch-cell current sensing scheme for fast line-embedded response. The product operates at switching frequencies of 300 kHz to 2 MHz. It can easily maintain a steady output voltage even under varying load conditions.

The MP2162AGQHT-Z\'s operation involves switching a voltage drop across the MOSFET with a frequency determined by the control loop. When the MOSFET turns on, the current rises very quickly, thus creating the inductor current. When the MOSFET is in the off state, the inductor current ramps down, thus out the ideal regulated output voltage. Through this process, the output voltage is regulated and the MOSFET is conserved from overload.

The MP2162AGQHT-Z provides a complete power solution for powering a wide range of applications. It has a wide input voltage range of 4.5 V to 28 V and a broad output voltage range of 3.3 V to 14 V with a convenient power good pin. Its integrated current-mode control and protection features enable an efficient and reliable circuit with an output of up to 3 A. Its optimized internal power dissipation makes it a perfect choice for space-constrained applications. Its advanced current sensing method, AVP circuitry and adaptive on-time control makes it capable of operating over a wide input voltage range and provide a high-efficiency solution.

The MP2162AGQHT-Z is a reliable and cost-effective DC DC switching regulator in the PMIC - Voltage Regulators - DC DC Switching Regulators family. It has the ability to provide a steady output voltage even under varying load conditions and offers multiple protection features. It is an ideal power solution for handheld applications, cellular phones and mobile data terminals requiring high-efficiency, reliable and low power DC DC conversion.
