1 / 43 page This is information on a product in full production. October 2012 Doc ID 022098 Rev 3 1/43 43 L7986TA 3 A step-down switching regulator Datasheet − production data Features ■ 3 A DC output current ■ 4.5 V to 38 V input voltage ■ Output voltage adjustable from 0.6 V ■ 250 kHz switching frequency, programmable up to 1 MHz ■ Internal soft-start and enable ■ Low dropout operation: 100% duty cycle ■ Voltage feed-forward ■ Zero load current operation ■ Overcurrent and thermal protection ■ HSOP8 package ■ Guarantee overtemperature range (-40 °C to 125 °C) Applications ■ Automotive: – Car audio, car infotainment ■ Industrial: – PLD, PLA, FPGA, chargers ■ Networking: XDSL, modems, DC-DC modules ■ Computer: – Optical storage, hard disk drive, printers ■ LED driving Description The L7986TA is a step-down switching regulator with 3.7 A (min.) current limited embedded power MOSFET, so it is able to deliver up to 3 A current to the load depending on the application conditions. The input voltage can range from 4.5 V to 38 V, while the output voltage can be set starting from 0.6 V to VIN. 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. The HSOP package with exposed pad allows the reduction of RthJA down to 40 °C/W. HSOP8 exposed pad www.st.com |
