NCV8843MNR2GEVB: Buck Regulator Demonstration Evaluation Board

Overview

The NCV8843 Demonstration Board provides a convenient way to implement and evaluate a complete practical buck regulator design. No additional components are required other than the DC input source and load. The board has an input voltage range of 5 V - 16 V and is preset for a nominal output voltage of 3.3 V. Included are SHDNB and SYNC terminals for logic on-off control of the regulator and synchronization of the internal controller to an external frequency source in place of the internal 340KHz oscillator.
