Introduction

AI Translation

The TPS4030x is a family of cost-optimized synchronous buck controllers that operate from 3V to 20V input voltage. This controller implements a voltage-mode control architecture with input voltage feed-forward compensation for immediate response to input voltage changes. The fixed switching frequency is 300KHz, 600KHz, or 1.2MHz. A Frequency Spread Spectrum (FSS) feature is incorporated into the switching frequency to significantly reduce peak EMI noise, making it easier to meet EMI standards. The TPS4030x offers multiple user-programmable features, including soft-start, overcurrent protection (OCP) level, and loop compensation.
