Working Principle

The LM2633MTD/NOPB is a high performance, low noise, low power buck-boost switching regulator. The device is designed to provide a wide range of output voltages with an adjustable voltage range spanning from 0.5 to 16V.The component utilizes hysteretic bipolar cycle skipping control to regulate the output voltage in applications where line and load variations cause the input current to exceed the output load. By performing this, it ensures that the output voltage is maintained within a specific, low-noise voltage range, even during line and load fluctuations. The component has two main working modes, buck mode and boost mode. In buck mode, the output voltage is less than the input voltage, while in boost mode, the output voltage is higher than the input voltage. This allows the component to step up or step down the voltage, making it suitable for use in situations where a wider input voltage range is necessary. In addition, the component also includes a variety of protection features, including short circuit protection, over-voltage protection, under-voltage protection and over-temperature protection. It also includes an external current sense resistor allowing additional current prevention measures to be implemented.
