Description
The L5988D is a monolithic step down power switching regulator able to deliver a continuous output current of 4 A to the load in most of the application conditions limited only by the thermal performance. The device is able to deliver more than 5 A to the load for a maximum time which is dependent on the thermal impedance of the system and the specific operating conditions).

Features
• 4 A output current (more than 5 pulsed)
• Operating input voltage from 2.9 V to 18 V
• External 1.8 V ± 2% reference voltage
• Output voltage from 0.6 to input voltage
• MLCC compatible
• 200 ns TON
• Programmable UVLO matches 3.3 V, 5 V and 12 V bus
• FSW programmable up to 1 MHz
• Voltage feed forward
• Zero load current operation
• Programmable current limit on both switches
• Programmable sink current capability
• Pre-bias start up capability
• Thermal shutdown

Applications
• Consumer: STB, DVD, LCD TV, VCR, car radio, LCD monitors
• Networking: XDSL, modems, routers and switches
• Computer and peripherals: printers, audio / graphic cards, optical storage, hard disk drive
• Industrial: DC-DC modules, factory automation
