Description
General part information
TPS40303 Series
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.
The frequency spread-spectrum (FSS) feature adds to the switching frequency, significantly reducing the peak EMI noise and making it much easier to comply with EMI standards.
The TPS4030x offers design with a variety of user-programmable functions, including soft start, overcurrent protection (OCP) levels, and loop compensation.
