TPS40303 Datasheet (Texas Instruments) - Synchronous Buck Controller

TPS40303, Synchronous Buck Controller

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 fix
