ST EVAL5983

DC/DC，步降3.3V3.3V ~ 18V

Overview

Description The L5983 is a step-down switching regulator with a 2.0 A (min.) current limited embedded Power MOSFET, so it is able to deliver an output current in excess of 1.5 A DC to the load. The input voltage can range from 2.9 V to 18 V, while the output voltage can be set starting from 0.6 V to VIN . Having a minimum input voltage of 2.9 V, the device is suitable also for a 3.3 V bus. Requiring a minimum set of external components, the device includes an internal 250 kHz switching frequency oscillator thatcan be externally adjusted up to 1 MHz. The VFQFPN package with an exposed pad allows reducing the RthJA down to approximately 60 °C/W.

Applications Consumer: STB, DVD, DVD recorder, car audio, LCD TV and monitors Industrial: chargers, PLD, PLA, FPGA Networking: XDSL, modems, DC-DC modules Computer: optical storage, hard disk drive, printers, audio/graphic cards LED driving
