DESCRIPTION  
Adjustable and Fixed Output Voltage  
The TPS6204x family of devices are high efficiency  
synchronous step-down dc-dc converters optimized for  
battery powered portable applications. The devices are  
ideal for portable applications powered by a single Li-Ion  
battery cell or by 3-cell NiMH/NiCd batteries. With an  
output voltage range from 6.0 V down to 0.7 V, the devices  
support low voltage DSPs and processors in PDAs,  
pocket PCs, as well as notebooks and subnotebook  
computers. The TPS6204x operates at a fixed switching  
frequency of 1.25 MHz and enters the power save mode  
operation at light load currents to maintain high efficiency  
over the entire load current range. For low noise  
applications, the devices can be forced into fixed  
frequency PWM mode by pulling the MODE pin high. The  
TPS6204x supports up to 1.2-A load current.
