The L6911CTR is a Pulse Width Modulation (PWM) controller used to regulate the output voltage of a DC/DC boost, buck or buck-boost converter. It is part of a larger family of DC/DC controllers from STMicroelectronics, the L6911x series, that provides a cost-effective solution for applications needing a wide range of output voltages. The L6911CTR is particularly suited for high-power applications, as it can supply up to 5A of current, and is highly efficient thanks to its low switching frequency, typically 30kHz.

The L6911CTR has a PWM frequency of 30 kHz, adjustable with an external resistor between 4.7kHz and 50 kHz. The internal voltage reference is 1.25V and its output voltage range is 2.5V to 15V. It also features a proprietary Soft-Start control for smooth start-up, over-voltage and over-current protection, and thermal shutdown.

The L6911CTR is used in a wide range of DC/DC application, such as notebook computers, tablet PCs, digital cameras, smartphones and other portable consumer electronics. It can also be used in a variety of industrial application, including motor control systems, robotics and automotive applications.

The working principle of the L6911CTR is simple: it regulates the output voltage of a DC/DC converter by adjusting the duty-cycle of the converter\'s control voltage. The control voltage is adjusted by the error amplifier, which compares the output voltage with the internal reference. The error signal then produces an output signal to the internal high/low side MOSFET switches, causing the MOSFETs to open or close at the appropriate times, thus controlling the output voltage.

The L6911CTR provides high accuracy and high efficiency, making it an ideal choice for many power management applications. It is also easy to use, with an intuitive design and well-documented data sheets.
