General Description

The TPS4030x is a family of cost-optimized synchronous buck controllers that operate from 3-V to 20-V input.

The controller implements a voltage-mode control architecture with input-voltage feed-forward compensation that responds instantly to a change in input voltage.

The switching frequency is fixed at 300 kHz, 600 kHz, or 1.2 MHz.
