TPS62135, TPS621351 High Accuracy 3-V to 17-V 4-A Step-Down Converters  
with DCS-Control™  
1 Features  
3 Description  
The TPS62135 and TPS621351 are high efficiency  
and easy to use synchronous step-down DC-DC  
converters, based on the DCS-Control™ Topology.  
The devices wide input voltage range of 3-V to 17-V  
makes it suitable for multi-cell Li-Ion as well as 12-V  
intermediate supply rails. The devices provide 4-A

current.  
The  
TPS62135  
Forced PWM or PWM/PFM operation  
automatically enters Power Save Mode at light loads  
to maintain high efficiency across the whole load  
range. With that, the device is well suited for  
applications that require connected standby  
performance, like ultra low power computers. With the  
MODE pin set to low, the switching frequency of the  
device is adapted automatically based on the input  
and output voltage. This technique is called  
Automatic Efficiency Enhancement (AEE™) and  
maintains high conversion efficiency over the whole  
operation range. It provides a 1% output voltage  
accuracy in PWM mode and therefore enables the  
design of a power supply with high output voltage  
accuracy.  
Typical switching frequency of 2.5MHz in forced  
PWM  
Precise ENABLE input allows

The device has a typical quiescent current of 18 µA.  
In shutdown mode the current is typically 1 µA and  
the output is actively discharged for TPS62135 while  
the output voltage discharge feature is disabled in  
TPS621351.
