Overview
The L7981 device is a step-down switching regulator with a 3.7 A (minimum) current limited embedded Power MOSFET, so it is able to deliver up to 3A current to the load depending on the application conditions. The input voltage can range from 4.5 V to 28 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 QFN and the HSOP packages with exposed pad allow reducing the RthJA down to 60℃/W and 40℃/W respectively.
Applications
- Consumer: STB, DVD, DVD recorder, car audio, LCD TV and monitors
- Industrial: PLD, PLA, FPGA, chargers
- Networking: XDSL, modems, DC - DC modules
- Computer: Optical storage, hard disk drive, printers, audio/graphic cards
- Suitable for LED driving
Key features
- 3 A DC output current, 4.5 V to 28 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
- VFQFPN 3×3 - 8L and HSOP8 package
