：MB39C326PW-G-ERE1，PMIC - - DC Switching Regulators。IntroductionMB39C326PW-G-ERE1 is a DC-DC switching regulator PMIC (Power Management Integrated Circuit). Its applications are used in a wide range of fields. It is a three-phase buck regulator.Application fieldMB39C326PW-G-ERE1 is mainly used for DC-DC conversion in computer systems, for example, servers, schools servers, communication servers and industrial servers. It can also be used for TV set box, HDD, panel PCs, and digital TVs. In addition, this device also applies to Notebook computers, Notebook Tablet PCs, and HDDs with Multiple Drives, as well as smaller devices such as PDA and phones.In terms of features and performance, the main features of MB39C326PW-G-ERE1 include built-in Linear Regulation, High-Efficiency Synchronous DC-DC Conversion, Over-Voltage Protection, Low-Voltage Output, Low Dropout Voltage, using an Unregulated Voltage Input, and Low Power Consumption. The performance characteristics of MB39C326PW-G-ERE1 includes:•High Efficiency (up to 96%)•High RMS Switching Frequency (up to 2MHz)•Lowest Start-up Voltage (1.5V)•Ultra Low Vdrop•High Output Voltage Accuracy (within ±2.5%)•Low Output Voltage Sweeping (±5%)•Wide Output Voltage Range (1.5V to 6V)•Automatic Shutdown•OTP ProtectionWorking PrincipleThe MB39C326PW-G-ERE1 is a 3-phase buck regulator PMIC. It consists of an Input voltage regulating circuit and an output voltage buck circuit, connected through a feedback loop. The input voltage regulating circuit and the output voltage buck circuit are separated, but regulate the output voltage through the feedback loop.The input voltage regulating circuit and the output voltage buck circuit are both operated by PWM logic, to achieve the optimal efficiency and output voltage regulation. The input and output circuits of the MB39C326PW-G-ERE1 are controlled by a PWM signal, as a feedback signal. The supply voltage is regulated and converted to anything between 1.5V and 6V.The MB39C326PW-G-ERE1 features Linear and Synchronous Regulation, which is one of the leading features on the market. Linear regulation reduces the switching noise and therefore improves efficiency. Synchronous Regulators reduce power loss, improve stability, and allow more flexibility in the power supply design.ConclusionThe MB39C326PW-G-ERE1 is a DC-DC switching regulator PMIC suitable for a wide range of applications. It is able to convert input voltages of anything between 1.5V and 6V. The device features Linear and Synchronous Regulation, which allows it to maintain a stable output voltage. The device\'s high efficiency, high RMS switching frequency and Over-Voltage protection make it an attractive solution for many consumer and industrial applications.
