DESCRIPTION  
The TPS2505 provides an integrated solution to meet USB 5-V power requirements from a 1.8-V to 5.25-V input  
supply. The features include a 5.1-V, 1100-mA boost converter, a 200-mA, 3.3-V LDO linear regulator and dual  
USB 2.0 compliant power outputs with independent output switch enable, current limit, and over-current fault  
reporting.  
The 1.8-V to 5.25-V input can be supplied by sources including DC/DC regulated supplies (e.g. 3.3 V), or  
batteries such as single cell Li+, two-cell or three-cell NiCd, NiMH or alkaline.  
The output trip current for the dual USB switches can be programmed via external resistors from as low as  
100 mA to as high as 1100 mA.  
An auxiliary 5.1-V output is provided, where the total current supplied by the USB outputs and the auxiliary by  
cannot exceed 1100 mA.
