L5983TR Product details

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

Features
■ 1.5A DC output current
■ 2.9V to 18V input voltage
■ Output voltage adjustable from 0.6V
■ 250kHz switching frequency, programmable up to 1MHz
■ Internal soft-start
■ Inhibit
■ Low dropout operation: 100% duty cycle
■ Voltage feed-forward
■ Zero load current operation
■ Over current and thermal protection
■ VQFN3x3-8L package

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