Description
General part information
TPS40345 Series
The TPS40345 is a synchronous buck controller that operates from 3-V to 20-V input and which can be used in cost-optimized applications. 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 600 kHz.
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 TPS40345 offers design with a variety of user-programmable functions, including soft-start, overcurrent protection (OCP) levels, and loop compensation.
