TPS40090-Q1

illustrate

The TPS40090 is a dual, three- or four-phase programmable synchronous buck controller for low-voltage, high-current 15-V distributed power supplies optimized for a 5 V supply application. A multi-stage converter provides a combination of input current ripple and output capacitance at low power stages, faster transient response to load steps, improved power handling and higher system efficiency.

Each stage can be maintained at a switching frequency of up to 1 MHz, in a valid registration of a ripple frequency of 4-AT input and a four-stage application output megahertz. A two-stage design work of 180° heterophase, a three-stage design work of 120° heterophase, and a four-stage design work of 90°, as shown in Figure 1.
