TPS2505SPAS093C –DECEMBER 2009–REVISED SEPTEMBER
TPS2505 Integrated Dual USB Switches, Boost Converter and LDO Features 3 DescriptionThe TPS2505 device provides an integrated Integrated Synchronous Boost Converter, LDO, to meet USB 5-V power requirements froma 1.8-Vand Dual USB Current-Limited Switches 5.25-V input supply. The features includea 5.1-V,• 1.8-Vto 5.25-V Input Voltage 1100-mA boost converter,a 200-mA, 3.3-V(2.2-V Minimum Start-Up Voltage) linear regulator and dual USB 2.0 compliant power
outputs with independent output switch enable,• Adjustable Independent USB Current Limit
current limit, and overcurrent fault reporting.– 100 mAto 1100 mA
The 1.8-Vto 5.25-V input canbe suppliedby• Auxiliary 5.1-V Output
including DC-DC regulated supplies (for example,• 3.3-V Linear Regulator Output V),or batteries such as single cell Li+, two-cellor• Inrush Current< 100 mA three-cell NiCd, NiMHor alkaline. Minimal External Components Required The output trip current for the dual USB switches can• Deglitched Independent Fault Reporting be programmed through external resistors from as
lowas 100 mAtoas highas 1100 mA.• Small 5-mm× 5-mm QFN-20 Package Industrial Temperature Range An auxiliary 5.1-V outputis provided, where the total
current suppliedby the USB outputs and the auxiliary
