产品概述

描述

The A6984 is a step-down monolithic switching regulator able to deliver up to 400 mA DC. The output voltage adjustability ranges from 0.9 V. The fixed 3.3 V VOUT requires no external resistor divider. The “low consumption mode” (LCM) is designed for 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 almost constant over the load current range, serving low noise application specifications such as car audio/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 make the size of the application compact. Pulse-by-pulse current sensing on the low-side power element implements effective constant current protection. The package lead finishing guarantees side solderability, thus allowing visual inspection during manufacturing.
