MPQ4432GL-P is a highly integrated solution for Voltage Regulators in PMICs. With a wide range of operating voltages and current ratings, this DC-DC switching regulator is designed for applications such as voltage converters, step down converters, Point of Load (PoL) regulators and other high current power supplies in a variety of small or portable electronics.

The MPQ4432GL-P regulator utilizes an advanced cold-started non-synchronous rectification boost topology, which provides an adjustable output voltage range from 0.8V to 5.5V and current ratings up to 600mA with a high efficiency of up to 90%. The unit has an input voltage range of 1.8V to 6V and utilizes low input current ripple, which enables low EMI and low noise operation. In addition, it features selectable 3V, 5V and 12V output voltage channels, an I2C current limit control and an active current clamping technique which allows the device to protect itself against current surge up to 20A.

The MPQ4432GL-P also features a built-in power good (PG) pin which alerts a system when the output voltage is below a certain point. The unit also has adjustable start-up, soft-start and response times, and utilizes a current mode architecture which provides stable operation in the presence of large output capacitances. Additionally, the unit uses multiple output tracking and droop modes to ensure that the regulated output does not undergo excessive changes during input voltage transients.

In terms of physical layout and installation, the MPQ4432GL-P has an overall dimension of 3.62 x 5.3 mm and is available in a variety of packages, such as a 4-pin with a 4-position pitch and a 8-pin with an 8-position pitch. The unit also features an operating temperature range of -40 oC to 125 oC, making it suitable for a wide range of applications.

The MPQ4432GL-P DC-DC switching regulator supports both PWM and spread spectrum frequency control, enabling the user to select the optimal switching frequency for their application. The unit also supports frequency synchronization with external signals, allowing for the synchronization of multiple regulators. Furthermore, the MPQ4432GL-P has a selectable bypass feature which reduces the overall power consumption of the system.

In summary, the MPQ4432GL-P DC-DC switching regulator is an ideal solution for small and portable electronic devices, such as smartphones and tablets, due to its wide input voltage range, high current ratings and robust protection features. With its adjustable operating frequency, low input current ripple and power saving bypass feature, the MPQ4432GL-P regulator is a great choice for applications requiring high reliability and efficient power conversion.
