The MPQ2143DJ-AEC1-Z is an integrated circuit (IC) designed and manufactured by Monolithic Power Systems (MPS) and is a regulating voltage switching DC-DC converter. This device is designed to provide a regulated output voltage in the range of 1.5V to 5.5V and is suitable for a variety of applications. The MPQ2143DJ-AEC1-Z belongs to the category of PMIC - Voltage Regulators - DC DC Switching Regulators, as it is a voltage regulator that takes an input voltage and converts it to a selectable, regulated output voltage.The MPQ2143DJ-AEC1-Z is a current-mode, multi-phase interleaved switching converter. Each of the two phase legs can be independently controlled and support phase shedding modes. This means that the output power can be reduced very quickly in response to an overload condition, by controlling the phase on/off duty cycle ratio to achieve a balance between the output voltage and current. The MPQ2143DJ-AEC1-Z is designed to work at high efficiency, so it can be used in applications such as servers, storage, network switching and power supplies.The MPQ2143DJ-AEC1-Z has a comprehensive feature set, including a programmable current limit, a power up sequence, over-voltage protection, output disconnect detection and feedback loss detection. It also supports input voltage scaling, allowing the input voltage range to be tailored to fit a wide range of applications.The MPQ2143DJ-AEC1-Z has a selectable maximum switching frequency of up to 2 MHz, making it suitable for a variety of high-frequency applications. It also supports a low-noise mode, allowing it to be used in applications where low-noise operation is essential. The device is also designed to support an external clock, allowing for synchronised operation with other components in the system.The MPQ2143DJ-AEC1-Z is designed to work with a wide range of input and output voltages, making it a suitable choice for applications such as mobile phones, tablets, laptops and power supplies. The input current is low, allowing the device to be used with applications where the input voltage is limited.The MPQ2143DJ-AEC1-Z has a number of protection features, including output over-current protection, output under-voltage lockout and over-voltage protection. The MPQ2143DJ-AEC1-Z also supports different modes of operation, such as forced continuous conduction mode and forced discontinuous conduction mode. The device is also designed to be thermal and ESD tolerant, protecting against damage from an environment with fluctuating or excessive temperatures.In summary, the MPQ2143DJ-AEC1-Z is a high-performance, high-efficiency DC-DC switching regulator, with a comprehensive feature set, suitable for a wide range of applications where high-frequency operations, low-noise operation and thermal protection are essential. The MPQ2143DJ-AEC1-Z operates with a wide range of input and output voltages and each phase can be independently controlled, allowing the output power to be reduced very quickly in response to an overload condition. The MPQ2143DJ-AEC1-Z also supports features such as over-voltage protection, output disconnect detection and feedback loss detection. Taken together, these features make the MPQ2143DJ-AEC1-Z an ideal choice for PMIC - Voltage Regulators - DC DC Switching Regulators applications.
