2A synchronous step-down switching regulator

L6986H Datasheet 38 V, 2 A synchronous step-down switching regulator with 30 μA quiescent current Product status link L6986H Features • 2 A DC output current • 4 V to 38 V operating input voltage • Low consumption mode or low noise mode • 30 µA IQ at light-load (LCM VOUT = 3.3 V) • 8 µA IQ-SHTDWN • Adjustable fSW (250 kHz - 2 MHz) • Fixed output voltage (3.3 V and 5 V) or adjustable from 0.85 V to VIN • Embedded output voltage supervisor • Synchronization • Adjustable soft-start time • Internal current limiting • Overvoltage protection • Output voltage sequencing • Peak current mode architecture • RDS(on) HS = 180 mΩ, RDS(on) LS = 150 mΩ • Thermal shutdown Applications • Designed for 12 V and 24 V buses • Programmable logic controllers (PLCs) • Decentralized intelligent nodes • Sensors and low noise applications (LNM) Description The L6986H 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. Thanks to the Pchannel 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 th.
