Product Description

The L6986TR is a step-down monolithic Switching Regulator able to deliver up to 2A DC. The output voltage adjustability ranges from 0.85V 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, 12 and 24V 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 overload current range, meeting the low noise application specification. The output voltage supervisor manages the reset phase for any digital load (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.
