Product overview
概要
The STEVAL-ISA200V1 product evaluation board is based on the A6984 high-efficiency monolithic synchronous step-down regulator, capable of delivering up to 400 mA of DC current. The fixed 3.3 V output requires no external resistor divider. The A6984 is especially suited for automotive systems. The low consumption mode (LCM) is designed for automotive applications that remain active while the car is parked, maximizing efficiency at light load with controlled output voltage ripple. The low noise mode (LNM) renders the switching frequency nearly constant over the load current range, serving low noise application specifications such as audio and sensors. The PGOOD open collector output can implement output voltage sequencing during the power-up phase. The synchronous rectification, designed for high efficiency at medium-heavy load, and the high switching frequency capability ensure a compact application size. Pulse-by-pulse current sensing on the low-side power element implements effective constant current protection.
