DESCRIPTION
Thanks to the P-channel MOSFET high-side power element, the device features 100% duty cycle operation. 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 specification. The output voltage supervisor manages the reset phase for any digital load (µC, FPGA).
