PMIC - Voltage Regulators - DC DC Switching Regulators are used to convert existing DC voltages into higher or lower levels, ensuring the clean and efficient power delivery of digital circuits. The BU90004GWZ-E2 is a multi-channel integrated DC DC switching regulator that is designed to meet the needs of various consumer electronics and automotive applications. This article provides an overview of the application field and working principle of the BU90004GWZ-E2.

The BU90004GWZ-E2 is a multi-channel integrated DC DC switching regulator that supports input voltages from 1.6V to 3.6V and outputs different output voltages in the range from 0.6V to 3.6V. It also has an adjustable switching frequency from 200kHz to 2.4MHz. The regulator adopts a voltage mode control and Pulse Width Modulated (PWM) control approach, and utilizes a symmetrical drive FET architecture to provide Peak Current Mode (PCM) and Low RDS (on) protection.

The regulator boasts a wide range of features, making it suitable for a variety of applications. Its wide input voltage and adjustable switching frequency capabilities allow it to be used in automotive applications such as automotive power supplies, navigation systems, and advanced driver assistance systems. Its PWM control approach also makes it suitable for consumer electronics such as cameras, laptops, tablets, and other portable devices. Its PCM and Low RDS (on) protection provide added protection, allowing the regulator to be used in medical and industrial applications as well.

The BU90004GWZ-E2 is a synchronous DC DC switching regulator that uses a Pulse Width Modulated (PWM) control approach. Its Pulse Width Modulated (PWM) control approach allows the regulator to precisely control both the input and output voltages, ensuring that the output voltage remains stable, regardless of input voltage fluctuations. The regulator also features an adjustable switching frequency, allowing the user to optimize the output voltage and efficiency. The adjustable frequency also helps to prevent EMC problems, reducing noise in the system and providing a stable power supply.

The BU90004GWZ-E2 also features Peak Current Mode (PCM) and Low RDS (on) protection, providing over current and over temperature protection. The PCM protection is triggered when the current limit is exceeded, reducing current flow and providing an additional layer of protection for the system. The Low RDS (on) protection will shut off the regulator and protect it from damage if the voltage exceeds the maximum rating. This helps to ensure that the regulator will remain in a safe state, even in the event of an overload.

In conclusion, the BU90004GWZ-E2 is a multi-channel integrated DC DC switching regulator that is suitable for a variety of applications, from automotive applications to medical and industrial applications. It offers a PWM control approach and adjustable switching frequency, PCM and Low RDS (on) protection, making it an ideal choice for those looking for an efficient and reliable power supply solution.
