Description
The R6986 device is a step-down monolithic switching regulator able to deliver up to 2 A DC. The output voltage adjustability ranges from 0.85 V to VIN. The 100% duty cycle, the wide input voltage range and the large ambient temperature range make it ideal for aerospace and defense applications. The “Low Consumption Mode” (LCM) is designed for always-on applications, 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. 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. HTSSOP16 (RTH = 40 °C/W)
