The SC2672STRT from DatasheetCatalog is a DC-DC switch controller, specially designed to provide a fast current regulation loop when controlling DC-DC Buck switching converters for an array of application fields. This device is highly versatile and has wide selections of available features throughout its entire range of power supplies.

Usually, this DC-DC switch controller is used in tandem with a switching regulator and provides a current to regulate the switching frequency and the output voltage. This provides a stable and reliable output, and the control loop that is created remains at a minimum, while offering impressive performance.

In terms of applications, the SC2672STRT is a great choice for DC-DC power conversion applications in various industries. Some of the common places where this controller is used are in telecom applications, medical devices, automotive electronics and even space industry applications.

The SC2672STRT also has other distinct features which make it optimal to use in a number of conditions. For instance, it supports a wide range of voltage ratings from 0.67V to 4.5V, and its switching frequency can be precisely adjusted from 500kHz to 2.4Mhz. Furthermore, its operating temperature range is -40 degrees Celsius to 100 degrees Celsius and its supply voltage range runs from 2.7V to 5.5V.

Now on to the SC2672STRT’s working principle. This device uses a current regulation loop in order to determine the correct output voltage required. In simple terms, the current regulation loop senses the output voltage of the power converter and then commands the gate driver to adjust the current in the switch accordingly. In turn, the output voltage is regulated until it reaches the required level.

In terms of features, this DC-DC switch controller offers a wide array of features, such as PWM/PFM control mode, adjustable deadband, adjustable frequency loop filter time constant, over-current and under-voltage lockout protection, thermal protected switch and prebiased voltage operation. Moreover, the SC2672STRT can also employ a voltage discharge and current slew rate control.

Overall, the SC2672STRT is an optimal solution for catering different applications requiring voltage regulation, with plenty of feature selection to make sure it fits within the customers’ requirements. The working principle behind this DC-DC switch controller also provides a reliable current regulation mode which makes reliable power conversion every time.
