Integrated Circuit Chip MAX16903SAUE33/V+ 2.1MHz High-Voltage 1A Mini-Buck Converter

Product Description Of MAX16903SAUE33/V+

MAX16903SAUE33/V+ is a small, synchronous buck converter with integrated high-side and low-side switches. MAX16903SAUE33/V+ device is designed to deliver 1A with input voltages from +3.5V to +28V, while using only 25μA quiescent current at no load. Voltage quality can be monitored by observing the PGOOD signal. The MAX16903SAUE33/V+ can operate in dropout by running at 97% duty cycle, making it ideal for automotive and industrial applications.
