FEATURES  
DESCRIPTION  
•
•
•
Wide Input Voltage Range 2V to 15V  
Up to 96% Efficiency  
The TPS6212X device family is a high efficient  
synchronous step down DC-DC converter optimized  
for low power applications. It supports up to 75mA  
output current and allows the use of tiny external  
inductors and capacitors.  
Power Save Mode with 11 µA Quiescent  
Current

Output Current 75mA  
Output Voltage Range 1.2V to 5.5V  
Up to 800kHz Switch Frequency  
Synchronous Converter, no External Rectifier  
Low Output Ripple Voltage  
The wide operating input voltage range of 2V to 15V  
supports energy harvesting, battery powered and as  
well 9V or 12V line powered applications.  
With its advanced hysteretic control scheme the  
converter provides power save mode operation. At  
light loads the converter operates in PFM mode  
(pulse frequency modulation) and transitions  
automatically in PWM (pulse width modulation) mode  
at higher load currents. The Power Save Mode  
maintains high efficiency over the entire load current  
range. The hysteretic control scheme is optimized for  
low output ripple voltage in PFM mode in order to  
reduce output noise to a minimum. It consumes only  
10uA quiescent current from VIN in PFM mode  
operation.  
100% Duty Cycle for Lowest Dropout

Low Power RF Applications  
Ultra Low Power Microprocessor  
Energy Harvesting  
An open drain power good output is available in the  
TPS62120 and indicates once the output voltage is in  
regulation.  
Industrial Measuring  
TPS62120 has an additional SGND pin which is  
connected to GND during shutdown mode. This  
output can be used to discharge the output capacitor.  
The TPS62120 is available in a small 3×3 mm2 8 pin  
SOT 23 package and the TPS62122 in a 2×2 mm2 6  
pin SON package.
