L6984 Synchronous Step-Down Switching RegulatorsSTMicroelectronics L6984 Synchronous Step-Down Switching Regulators are able to deliver up to a 400mA DC. The output voltage adjustability ranges from 0.9V. The fixed 3.3V V OUT requires no external resistor divider. The Low Consumption Mode (LCM) is designed for applications active during car parking. The LCM 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. This serves low noise application specifications like car audio/sensors. The P GOOD 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 low-side power element implements an effective constant current protection.
