The SC633ULTRT is a monolithic switching regulator that offers an exceptionally high efficiency with low output voltage ripple while providing complete protection features. It is part of a family of voltage regulators, specifically categorized as DC DC Switching Regulators, that are predominately used in industrial control, power supply, and power conversion applications.

The SC633ULTRT operates with a wide input voltage range from 4.5V to 36V, and provides a regulated output from 3.3V to 36V depending on the specific device variant. The SC633ULTRT additionally has a high efficiency power topology that boosts the input voltage to a higher output voltage making it ideal for industrial control, motor control and robotic systems.

The SC633ULTRT also provides integrated protection features such as over current protection (OCP), overvoltage protection (OVP), undervoltage protection (UVP), and thermal shutdown (TSD) giving the user a comprehensive solution with comprehensive fault protection while also providing over-temperature protection. Additionally, the SC633ULTRT has a current limit that prevents output current surge in the event of a short-circuit condition.

The SC633ULTRT works on a pulse-width modulation (PWM) topology that utilizes a high-frequency oscillator and an error amplifying comparator to produce a current-mode modulation signal. This current-mode modulation signal is then sent to the PWM controller, which drives the switching FETs with the correct pulse widths to produce an output voltage based on user requirements. This system ensures a high efficiency power topology that is adjustable to the input voltage range and user requirements.

The SC633ULTRT also offers an externally adjustable switching frequency of up to 500kHz, which allows the current limit to be set to the maximum output current. This feature also enables designers to reduce the size and cost of external components by rejecting the output current ripple and by optimizing the EMI performance. Additionally, the SC633ULTRT offers an adjustable soft-start time of up to 500ms to provide a linear output voltage start-up ramp.

To maximize efficiency and performance, the SC633ULTRT integrates leading-edge switching technologies such as zero-voltage switching (ZVS) and synchronous rectification. With ZVS, the FETs are turned on and off in such a way that the voltage spike during switching is minimized, reducing switching losses and improving power efficiency. The synchronous rectification technology suppresses the reverse current from the output capacitor and improves energy efficiency.

The SC633ULTRT is designed to meet the highest safety standards and is well-suited for a variety of applications including industrial control, power supply, and power conversion. Its integrated features, wide input voltage range, adjustable synchronous frequency and multiple protection feature combine to make the SC633ULTRT a powerful solution for many applications.
