TPS54314PWPR

TPS5430DDARG4 Description
The TPS543x is a 3-A, step-down (buck) regulator with an integrated high-side n-channel MOSFET.
The TPS5431 is intended to operate from power rails up to 23 V and the TPS5430 up to 36 V.
These devices implement constant-frequency voltage-mode control with voltage feed forward for improved line regulation and line transient response. Internal compensation reduces design complexity and external component count. TPS5430DDARG4
