The STR-X6759F is a PMIC (Power Management IC) configuration of a voltage regulator with offline switcher operating in AC to DC conversion mode. It is designed to provide a stable and regulated voltage of 5.0V @ 1.5A from an input between 15V and 35V AC. It has been developed as a discrete component solution as an alternative to conventional linear voltage regulator applications and provides higher performance and reliability.

The STR-X6759F is a highly efficient integrated switching regulator with features such as fixed or adjustable output voltage, adjustable switching frequency, short circuit protection, and programmable current limit. This makes it ideal for powering any device that needs a constant and reliable 5.0V DC output, such as microcontrollers, communication modules, sensors, and other electronic components.

The STR-X6759F is designed around a buck converter topology, with a full bridge rectifier configuration. The buck converter is capable of converting Alternating Current (AC) to Direct Current (DC) with a higher accuracy and stability than a traditional linear regulator. The buck converter works by using a MOSFET switch, which is opened and closed to control the output voltage, and a control circuit to regulate the on-time of the MOSFET switch. As the input voltage, or the load current, changes, the control circuit adjusts the on-time of the MOSFET switch accordingly to maintain the desired output voltage.

The STR-X6759F operates in two stages. In the first stage, the MOSFET switch is turned on and off to regulate the output voltage. During this period, the MOSFET switch is turned on for a certain amount of time for each cycle and then turned off for the remainder of the cycle to provide the desired output voltage. This is known as \'pulse width modulation\', where the output voltage is inversely proportional to the \'on-time\' of the MOSFET switch.

In the second stage, the feedback control loop monitors and adjusts the current limit and output voltage. This feedback loop is designed to ensure that the output voltage remains constant and that the device is operating safely and within the current limit set by the user. The feedback loop keeps the on-time of the MOSFET switch in the optimal range to ensure a stable output voltage, and also monitors and adjusts the current limit to prevent any risk of overloading the device.

The STR-X6759F is designed to operate efficiently and safely in various applications. It is ideal for embedded applications such as handheld gaming devices, portable entertainment systems, home appliances, and industrial or medical devices. It can also be used to power embedded microcontrollers and other application specific integrated circuits (ASICs). It has an addiitonal feature that it can sense the AC voltage and regulate the output voltage accordingly

The STR-X6759F is a great choice for applications that require efficient and reliable power conversion from AC to DC. It is easy to design and integrate into existing systems, and provides a simple, low-cost solution for voltage regulation. With its integrated protection features and adjustable switching frequency, it can handle a variety of different loads and conditions, making it an ideal choice for a wide range of applications.
