NDP13802QB

NDP13802QB is a high efficiency, monolithic synchronous step-down DC/DC converter utilizing a jitter frequency mode control architecture. Capable of delivering up to 8A continuous load with excellent line and load regulation. The device operates from an input voltage range of 7.5V to 30V and provides an adjustable output voltage from 3.3V to 25V. The NDP13802QB features short circuit and thermal protection circuits to increase system reliability. The internal soft-start avoids input inrush current during startup. The NDP13802QB require a minimum number of external components and a wide array of protection features to enhance reliability. The NDP13802QB is a high efficiency, monolithic, synchronous step-down DC/DC converter utilizing a jitter frequency, average current mode control architecture. Average current mode control enables fast and precise control of the output current. It operates through a wide VIN range and regulates with low quiescent current. An error amplifier compares the output voltage with an internal reference voltage of 1.0V and adjusts the peak inductor current accordingly. Overvoltage and undervoltage comparators will turn off the regulator.
