L6917BD is a high performance, low cost synchronous buck control IC from STMicroelectronics, ideal for a wide range of applications requiring a step-down DC/DC converter.

This controller can be used for a wide range of different applications that require a step-down DC/DC converter, including industrial, consumer and telecom applications. It is a highly efficient device that provides excellent regulation of output voltage, as well as current monitoring and protection features. With its low quiescent current, the L6917BD can save considerable power. It also features an internal synchronous gate drive, allowing for efficient power conversion without the need for external components.

The L6917BD is a synchronous buck DC/DC step-down current controller. It features an integrated voltage regulator, allowing it to regulate the output voltage of the system. This is done via a Pulse Width Modulation (PWM) signal, with the controller generating a PWM signal from the input voltage. The duty cycle of the signal is then adjusted depending on the output voltage, allowing for maximum efficiency when regulating the output.

The controller also features over current and over temperature protection, which protects the system from damage due to sudden high currents or thermal overload. Furthermore, the L6917BD also integrates a phase-locked loop (PLL) to ensure stable output frequency.

In terms of design, the L6917BD has been designed for easy integration into a variety of different systems. It is a low-profile part measuring just 4.6 x 6.7 mm and is pin compatible with STMicroelectronics\' previous parts. It also integrates a distributed loop compensation to minimize external component count.

The L6917BD is an ideal solution for a variety of applications requiring a step-down DC/DC converter. It offers excellent regulation of output voltage and current monitoring, as well as protection features, allowing it to be used in a wide range of industrial, consumer and telecom applications.
