The MPQ2143DJ-Z is a DC DC switching regulator, which is categorized under PMIC -- Voltage Regulators. This regulator is designed specifically for micro-power applications. It is highly integrated and offers very high efficiency, making it an ideal choice for portable and handheld applications that require low power levels.The MPQ2143DJ-Z operates as a synchronous step-down DC/DC converter, providing up to 3 A of continuous output current at up to 0.9 V. It includes an internal adjustable 0.8 V reference, internal clock and adjustable switching frequency. It also features Power-OK set regulated 0.9 V output voltage and programmable soft-start.The MPQ2143DJ-Z is a high-efficiency regulator that only draws a small quiescent current, which is utmost important for applications which are battery powered. It features a 65 dB PSSR at the upper frequency of 300kHz, thus allowing the designer to leave the output slightly undershot at light loading. It has programmable output voltage, adjustable switching frequency and wide-input voltage range of 2.3 V to 5.5 V, making it suitable for a number of applications.The MPQ2143DJ-Z regulator utilizes synchronous rectification to achieve high efficiency in a very small size. It has a spread-spectrum control feature that helps to minimize EMI radiation in the circuit. The output voltage can also be adjusted with a 0.5 % accuracy, which allows for high precision power management in demanding applications.The package size of the MPQ2143DJ-Z is very small and can fit easily on the application even if the device requires high integrated power requirements. It features low dropout voltage, low ESR requirement and provides the flexibility to the designer to use external components.In summary, the MPQ2143DJ-Z is a highly integrated, high performance DC DC switching regulator, operating as a synchronous step-down DC/DC converter, providing up to 3 A of continuous output current. It has a wide input voltage range, low quiescent current, and high efficiency. Its small package size and packaging flexibility make it an ideal choice for portable applications which require low power levels.
