DESCRIPTION  
The TPS62203 is a high-efficiency synchronous step-down converter ideally suited for portable systems powered  
by 1-cell Li-Ion or 3-cell NiMH/NiCd batteries. The device is also suitable to operate at a standard voltage rail.  
The device is ideal to power low voltage DSPs and processors used in PDAs, pocket PCs, and smart phones.  
Under nominal load current, the device operates with a fixed switching frequency. At light load currents, the part  
enters the power save mode operation and the switching frequency is reduced; therefore, it achieves the highest  
efficiency over the entire load current range. The TPS62203 needs only three small external components. An  
advanced fast response voltage mode control scheme achieves superior line and load regulation with small  
ceramic input and output capacitors.

(2) Processing is per the Texas Instruments commercial production baseline and is in compliance with the Texas Instruments Quality  
Control System in effect at the time of manufacture. Electrical screening consists of DC parametric and functional testing at room  
temperature only. Unless otherwise specified by Texas Instruments AC performance and performance over temperature is not  
warranted. Visual Inspection is performed in accordance with MIL-STD-883 Test Method 2010 Condition B at 75X minimum.
