The output voltage adjustability ranges from 0.85 V to VIN. Thanks to the P- channel MOSFET high-side power element, the device features 100% duty cycle operation. The wide input voltage range meets the specification for the 5 V, 12 V and 24 V power supplies. The “low consumption mode” (LCM) is designed for applications active during idle mode, so it maximizes the efficiency at light-load with controlled output voltage ripple. The “low noise mode” (LNM) makes the switching frequency constant and minimizes the output voltage ripple overload current range, meeting the low noise application specifications. The output voltage supervisor manages the reset phase for any digital load (µC, FPGA). The RST open collector output can also 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 both power elements implements an effective constant current protection.
