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.
