The MPQ4487GU-AEC1-Z is a DC/DC switching regulator. It is a power management integrated circuit (PMIC) designed to provide stable, efficient and reliable DC/DC power conversion. It is a single chip solution that integrates a powerful MOSFET driver capable of providing up to 2.5A of current. It also has a wide input voltage range and is able to convert any input voltage between 2.5V and 24V into a fixed output voltage.

The MPQ4487GU-AEC1-Z is commonly used in applications such as external power supplies, AC/DC adapters, industrial and telecom power supplies, servers, and automotive power supplies. It has excellent EMI signature/immunity, integrated protection features, and is capable of operating in the most demanding environments.

The working principle of the MPQ4487GU-AEC1-Z is based on synchronous rectification and pulsewidth modulation (PWM) control. It uses synchronous rectification to minimize the power losses caused by rectification and to reduce the total cost of ownership. It is capable of operating as a Buck, Buck-Boost, or Boost regulator, depending on the input/output voltage levels. In Buck regulator mode, it converts the input voltage higher than the output voltage. In Buck-Boost mode, it is able to convert the input voltage lower or higher than the output voltage. In Boost mode, it is able to convert the input voltage lower than the output voltage.

The MPQ4487GU-AEC1-Z is a versatile and reliable power management solution. Its features, wide operating temperature range, and high efficiency make it well-suited for commercial and industrial applications. The device also has high accuracy current sensing, error amplifier compensation, and a wide range of fixed switching frequencies. It is well suited for space-constrained applications and can be used as a power supply for embedded systems and motor drives.
