Voltage regulators and linear voltage regulators are essential components for many applications. AS1351-BQFS-FF is a voltage regulator specifically designed for lead-free, hot-swap applications. It is an economical, highly integrated solution addressing many of the problems associated with power supply design, power system design and power management. This article will discuss the application field and working principle of AS1351-BQFS-FF Voltage Regulator.

The AS1351-BQFS-FF is a monolithic device designed for use in lead-free, hot-swap applications. It is equipped with two integrated LDO (low drop-out) linear regulators, one for cooling and one for powering. The device features a low-dropout voltage of 0.75V, an on-board voltage reference, an output accuracy of ±1%, a soft-start function, an overtemperature protection circuit, and a built-in overcurrent protection circuit. The device is also equipped with an output voltage trim function and a power good output. The device is available in a very small footprint (2.2mm x 2.2mm) package.

The AS1351-BQFS-FF Voltage Regulator is designed for use in high-performance computing applications, such as upcoming 4K ultra-high-definition (UHD) displays. It is designed to regulate the power to the processor, enabling the processor to maintain high performance levels even when there are fluctuations in the power supply voltage. The device also helps protect against unpredictable and irregular current spikes.

In addition to its applications in high-performance computing, the AS1351-BQFS-FF can also be used in server and storage applications, Electric vehicle charging applications, telecommunication and network equipment and also industrial process control. The device is designed to meet the reliability and robustness requirements of high-power data centers and other space-limited applications.

The AS1351-BQFS-FF includes two integrated LDO linear regulators, one for cooling and one for powering. The linear regulator is the core component of a voltage regulator, with the main purpose of converting lower input voltages to higher output voltages. The linear regulator operates by creating a voltage drop between the input voltage and the output voltage. This voltage drop is created using a series of resistors, which are controlled by the control circuit.

The AS1351-BQFS-FF voltage regulator also includes an on-board voltage reference, an output accuracy of ±1%, a soft-start function, an overtemperature protection circuit and a built-in overcurrent protection circuit. The voltage reference circuit helps to reduce variation in output voltage due to changes in line voltage, and helps to ensure stable operation over a wide range of temperatures. The accuracy is further enhanced by the on-chip voltage reference, which is designed to provide very tight regulation and stability.

The voltage regulator also includes a built-in soft-start function, which helps to reduce the amount of load current that can be drawn during start-up. The device also includes an Overtemperature Protection Circuit, which is designed to limit the maximum junction temperature. This helps to protect the device against excessive temperatures which can be caused by over-current conditions.

The voltage regulator also includes a built-in over-current protection circuit, which is designed to prevent damage to the device due to changes in the load current. The device also includes a power good output, which is driven to indicate when the output voltage matches the programmed level.

The AS1351-BQFS-FF Voltage Regulator is a highly integrated and economical solution for lead-free, hot-swap applications. It is designed to meet the needs of high-performance computing applications, as well as server and storage applications, Electric vehicle charging applications, telecommunication and network equipment and also industrial process control. The device is designed to provide accurate and reliable voltage regulation, with integrated features to ensure a robust and reliable solution.
