The L6717TR is a member of STMicroelectronics’ Switch Modes Regulator (SMR) controllers for DC-DC converters. The device belongs to the broad family of Special Purpose Voltage Regulators, which are used for a wide variety of applications, from embedded systems to Industrial Automation. It also makes perfect sense for use in Automotive and UPS applications as well.

The L6717TR works by delivering an input voltage to a power supply stage where it is converted into an output voltage that can be adjusted according to the desired application requirements. The device utilizes a proprietary Pulse Width Modulation (PWM) control loop to regulate the output current amplitude and voltage level while it is also equipped with protection features that allow it to guard against a wide range of unexpected events.

The L6717TR offers a simple and cost effective solution for applications that require a significant amount of current but no drastic voltage regulation. When compared to other voltage regulator controllers, the device stands out due to its capability to support peak current levels up to 20A, with integrated MOSFETs.

The L6717TR is designed for use in applications where high efficiency, good transient response and frequency control is essential. The device offers some degree of feedback control, to ensure stabilised voltage regulation, with precisely differentiable hysteresis control to avoid undesirable voltage instabilities or power consumption.

When used in a multi-phase architecture, the L6717TR stands out from other regulators. A feature called phase spreading helps to improve ripple and stability at high currents and helps to ensure an efficient operation. This makes the device ideal for redundant systems, where power supplies are daisy chained and isolated.

Due to its impressive capability to reduce destabilizing inrush currents, the L6717TR is ideal for use in heavy load applications such as Automotive, UPS and Industrial Automation systems. The device is well-suited for synchronous Buck, Buck-Boost and Isolated systems where unregulated DC voltage sources can be managed without the use of external components.

An additional feature to this device includes the presence of fast and overshoot protection, which helps to protect against inrush current spikes and accidental shorts occuring during the normal operation. This benefit can also be used to configure design safety as well, allowing for increased safety and stress free operation for longer durations.

There are many other advantages associated with the L6717TR that makes it one of the best voltage regulator controllers out there. It is flexible in design, it offers excellent efficiency and output voltage control, it is fast and reliable, and it comes with integrated integrated fast-channel TFETs for efficient multi-phase synchronization.

Overall, the L6717TR is a well-rounded Special Purpose Voltage Regulator controller for a wide range of applications in Automotive, Industrial Automation, Embedded Systems and UPS systems. With features such as feedback control, phase spreading, fast-acting transient protection, and integrated TFETs, the device has everything it takes to provide a robust and efficient power solution.
