TPS40303 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 pensation that responds instantly to a change in input voltage. The switching frequency is fixed at 300 kHz, 600 kHz, or 1.2 MHz.
