DC Power Distributed Systems
The TPS4009x is a two-, three-, or four-phase programmable synchronous buck controller that is optimized for
low-voltage, high-current applications powered by a 5-V to 15-V distributed supply. A multi-phase converter
offers several advantages over a single power stage including lower current ripple on the input and output
capacitors, faster transient response to load steps, improved power handling capabilities, and higher system
efficiency.
Each phase can be operated at a switching frequency up to 1-MHz, resulting in an effective ripple frequency of
up to 4-MHz at the input and the output in a four-phase application. A two-phase design operates 180 degrees
out-of-phase, a three-phase design operates 120 degrees out-of-phase, and a four-phase design operates 90
degrees out-of-phase as shown in Figure 1.
The number of phases is programmed by connecting the de-activated phase PWM output to the output of the
internal 5-V LDO. In two-phase operation the even phase outputs should be de-activated.
