TPS40090PW

illustrate

The TPS4009x is a two-, three-, or four-phase programmable synchronous buck controller optimized for low-voltage, high-current 15-V distributed power supply applications powered by a 5 V supply. A multi-stage converter provides many advantages including low power stage input current ripple and output capacitance, faster transient response load steps, improved power handling and higher system efficiency.

Each stage can be maintained at a switching frequency of up to 1 MHz, generating ripple frequencies at 4-AT input and a four-stage application output MHz in a valid register. A two-stage design work of 180° out-of-phase, a three-stage design work of 120 degrees out of phase, and a four-stage design work of 90 degrees, an outer phase.
