FEATURES  
DESCRIPTION  
The TPS62125 is a high efficiency synchronous step  
down converter optimized for low and ultra low power  
applications providing up to 300mA output current.  
The wide input voltage range of 3V to 17V supports  
four cell alkaline and 1 to 4 cell Li-Ion batteries in  
series configuration as well as 9V to 15V powered  
applications. The device includes a precise low power  
enable comparator which can be used as an input  
supply voltage supervisor (SVS) to address system  
specific power up and down requirements. The  
enable comparator consumes only 6µA quiescent  
current and features an accurate threshold of 1.2V  
typical as well as an adjustable hysteresis. With this  
feature, the converter can generate a power supply  
rail by extracting energy from a storage capacitor fed

scheme the  
Pin to Pin Compatible with TPS62160/70  
100% Duty Cycle Mode  
converter provides power save mode operation to  
maintain highest efficiency over the entire load  
current range. At light loads the converter operates in  
PFM mode (pulse frequency modulation) and  
transitions seamlessly and automatically in PWM  
(pulse width modulation) mode at higher load  
currents. The DCS - ControlTM scheme is optimized  
for low output ripple voltage in PFM mode in order to  
reduce output noise to a minimum and features  
excellent AC load regulation. An open drain power  
good output indicates once the output voltage is in  
regulation.
