L5985 2 A step-down switching regulator Datasheet - production data VFQFPN8 3 mm x 3 mm  Industrial: chargers, PLD, PLA, FPGA  Networking: XDSL, modems, DC-DC modules  Computer: optical storage, hard disk drive, printers, audio/graphic cards  LED driving Features  2 A DC output current  2.9 V to 18 V input voltage  Output voltage adjustable from 0.6 V  250 kHz switching frequency, programmable up to 1 MHz  Internal soft-start and inhibit  Low dropout operation: 100% duty cycle  Voltage feedforward  Zero load current operation  Overcurrent and thermal protection  VFQFPN8 3 mm x 3 mm package Description The L5985 is a step-down switching regulator with a 2.5 A (min.) current limited embedded Power MOSFET, so it is able to deliver up to 2 A DC current to the load depending on the application condition. 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 for a 3.3 V bus. Requiring a minimum set of external components, the device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz. Applications  Consumer: STB, DVD, DVD recorder, car The VFQFPN8 package with an exposed pad allows reducing the RthJA down to approximately 60 °C/W. audio, LCD TV and monitors Figure 1.
