Description

The L6986 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. 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 overload current range, meeting the low

noise application specification. The output voltage

supervisor manages the reset phase for any

digital load (

µC, FPGA, etc.). 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.
