The AP2014ASG-13 is a synchronous buck controller with maximum efficiency, which has advanced on-chip power MOSFETs and has varying functionality for different applications. It is designed to provide an adjustable output voltage for various electronic circuits. This device uses synchronous rectification for highly efficient regulator control. It is specifically designed for applications that require accurate voltage regulation and high accuracy in the presence of large load transients.

The main application field for the AP2014ASG-13 is typically DC-to-DC conversion, and a few applications include power management systems, digital signal processor core power, cyclic cell battery charger, laptop computer power converters, industrial instrumentation and server power supplies. This device also has applications in high reliability automotive systems such as engine management, and also in motion control systems.

The working principle of the AP2014ASG-13 is based on the synchronous switching of power between positive and negative supply rails. It has the ability to regulate an output voltage from 0.8V to 5.5V with an adjustable output current up to 8A. It also provides over-current protection, under-voltage lock-out, thermal shut-down, and programmable soft-start functions. The two high and low side power MOSFETs drive the switching of current from the input voltage rails to the output voltage. The peak switching frequency is also adjustable from 50kHz to 500kHz for various applications.

The AP2014ASG-13 is best suited for use as a DC-DC Switching Controller in Power Management ICs (PMICs). It ensures high efficiency and accurate voltage regulation, making it an excellent choice for applications that need to cope with both large changes in load and line transients. Its adjustable switching frequency and on-chip power MOSFETs make it particularly suitable for applications that require high system integration and cost savings.
