FEATURES  
DESCRIPTION  
DCS-ControlTM Architecture for Fast Transient  
Regulation  
The TLV62080 device is a synchronous step down  
converter with an input voltage range of 2.5V to 5.5V.  
The TLV62080 focuses on high efficient step down  
conversion over a wide output current range. At  
medium to heavy loads, the converter operates in  
PWM mode and automatically enters Power Save  
Mode operation at light load currents to maintain high  
efficiency over the entire load current range.  
2.5V to 5.5V Input Voltage Range  
100% Duty Cycle for Lowest Dropout  
Power Save Mode for Light Load Efficiency  
Output Discharge Function  
Power Good Output  
To address the requirements of system power rails,  
the internal compensation circuit allows a large  
selection of external output capacitor values ranging  
from 10µF up to 100uF effective capacitance. With its  
DCS-ControlTM architecture excellent load transient  
performance and output voltage regulation accuracy  
is achieved. The device is available in 2mm x 2mm  
SON package with Thermal PAD.  
Thermal Shutdown  
Available in 2x2mm 8-Pin SON Package  
For Improved Features Set, See TPS62080
