1.3 DESCRIPTION  
The  
TPS53851  
is  
a
multifunctional  
synchronous buck controller that can be  
configured to provide either a single-output  
two-phase power supply or a power supply  
that supports two independent outputs.  
Several TPS53851 controllers can be stacked  
up to a 16-phase multiphase single output  
power supply. Alternatively, several controllers  
providing multiple independent outputs can be  
synchronized in an interleaving pattern for  
improved input ripple current.  
• 36-pin QFN Package  
1.2 APPLICATIONS  
Graphic Cards  
Internet Servers  
Networking Equipment  
Telecommunications Equipment  
DC Power Distributed Systems  
The TPS53851 is capable of converting from a  
15-V input to a 0.7-V output at 1MHz.  
Each phase operates at a switching frequency  
of up to 1 MHz. The two phases in one device  
operate 180° out-of-phase. In a multiple device  
stackable configuration, the phase shift of the  
slaves, relative to a master, is programmable.
