This video demonstrates some of the features and capabilities of the NCV891330PD50GEVB evaluation board. The NCV891330 Low-Iq Dual-Mode Step-Down Regulator from ON Semiconductor is designed for Automotive, battery-connected applications that must operate with up to a 45V input supply. Depending on the output load, it operates either as a PWM Buck Converter or as a Low Drop-Out Linear Regulator, and is suitable for systems with low noise and Low Quiescent Current requirements often encountered in automotive driver information systems. Understand how to set-up and measure results for this evaluation board to optimize efficiency.
