PAM2316AGCADJ

Introduction

The PAM2316AGCADJ is a high-efficiency and synchronous step-down DC-DC converter, which presents a compact solution for restricted space and high performance applications. This device features the Synchronous Rectification Control and is suitable for portable and low voltage system applications.

Application Field

The PAM2316AGCADJ Switching Regulator feature a wide 4.5V to 28V input voltage range, and an output force/sense pins compliant with guidelines of the industry. Thanks to the Adaptive On-Time Control, this device is able to execute 1A of maximum output current at higher frequency with low output voltage ripple. Its embedded protections ensure high reliability capability and design flexibility.

Power management solutions that require less board space, more efficiency and smaller size are managed easily and effectively. The PAM2316AGCADJ Switching Regulator is ideal for distributed power work, because it provides a high efficiency, low cost and lower temperatures for high power applications.

Common applications include mobile phones, computers, consumer electronic products, TVs systems, and many other industrial power supply requirements.

Working Principle

In order to perform its job, the PAM2316AGCADJ Switching Regulator uses a built-in, temperature-compensated, Adaptive On-Time Control, which provides constant switching frequency over the full load range. In addition, it contains an internal current limit, over temperature protection, and short circuit protection features. The robust protection features ensure the part\'s reliable operation.

The PAM2316AGCADJ Switching Regulator includes high-side and low-side driver. The drivers synchronize the controller to provide a constant switching frequency with very low harmonic distortion. It is worth to note that the drivers are protected against voltage surge, under-voltage lockout, cycle-by-cycle current limiting, and thermal shutdown.

The internal Adaptive On-Time Control simplifies the design of the converter by eliminating the need for an additional resistor network, compensating loop, and other frequency-compensating components. It also enables for current mode control for lower output voltage ripple and fast transient response at a wide range of output voltage.

The output voltage is internally regulated by a linear regulator. The output voltage is slightly adjustable by the VOUT and VREG control pins. The PAM2316AGCADJ Switching Regulator also features an auto-restart mode, to ensure stable operation against input disturbances and output overloading.

Conclusion

The PAM2316AGCADJ Switching Regulator is a highly efficient DC-DC converter with a compact solution, suitable for a number of applications including mobile phones, computers, consumer electronics, and other industrial power supply requirements. This converter features the Synchronous Rectification Control, Adaptive On-Time Control, and an embedded protection, which simplify the design and provide high reliability.
