TPS5120 - Two-Phase Synchronous Buck DC/DC Controller

General Description

The TPS5120 is a dual channel, high-efficiency synchronous buck controller where the outputs run 180 degrees out of phase, which lowers the input current ripple, thereby reducing the input capacitance cost.

Key Features

  • such as undervoltage lockout, power good, overvoltage, undervoltage, and programmable short-circuit protection promote system reliability. Please be aware that an important notice concerning availability, standard warranty, and use in critical.
