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 thatcan be externally adjusted up to 1 MHz.
Features:
1. 2 A DC output current
2. 2.9 V to 18 V input voltage
3. Output voltage adjustable from 0.6 V
4. 250 kHz switching frequency, programmable up to 1 MHz
5. Internal soft-start and inhibit
6. Low dropout operation: 100% duty cycle
7. Voltage feedforward
8. Zero load current operation
9. Overcurrent and thermal protection
Applications:
1. Consumer : STB, DVD, DVD recorder, car audio, LCD TV and monitors
2. Industrial : chargers, PLD, PLA, FPGA
3. Networking : XDSL, modems, DC-DC modules
4. Computer: optical storage, hard disk drive, printers, audio/graphic cards
5. LED driving
