  • The STEVAL-ISA159V1 product evaluation board is based on L6984, a 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 L6984 is suited for home appliances, factory and building automation. The Low Consumption Mode (LCM) is designed for eco-friendly home appliances and automotive applications active during car parking, so it maximizes the efficiency at light load with controlled output voltage ripple. The Low Noise Mode (LNM) makes 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.
