Introduction

AI Translation

The TPS4030x is a series of cost-optimized synchronous buck controllers that can operate at input voltages from 3V to 20V. This controller implements a voltage-mode control architecture with input voltage feedforward compensation, enabling an immediate response to input voltage changes. The fixed switching frequencies are 300kHz, 600kHz, or 1.2MHz. The Frequency Spread Spectrum (FSS) feature is added to the switching frequency section, significantly reducing peak EMI noise and making it easier to meet EMI standards. The TPS4030x has various user-programmable functions, including soft start, overcurrent protection (OCP) level, and loop compensation. The OCP level can be programmed via a single external resistor connected from the LDRV pin to the circuit ground. During the initial power-up process, the TPS4030x will enter the calibration phase, measure the LDRV pin voltage, and set the internal OCP voltage level. During operation, the device can determine whether an overcurrent condition occurs by comparing the programmed OCP voltage level with the voltage drop across the low-side FET when powered on. Then, the TPS4030x will enter the shutdown and restart cycles until the fault is eliminated. The TPS4030x is a family of cost-optimized synchronous buck controllers providing high-end features to construct high-performance DC–DC converters. Prebias capability eliminates concerns about damaging sensitive loads during start-up. Programmable overcurrent protection levels and hiccup overcurrent fault recovery maximize design flexibility and minimize power dissipation in the event of a prolonged output short. The Frequency Spread Spectrum (FSS) feature reduces peak EMI noise by spreading the initial energy of each harmonic along a frequency band, thus giving a wider spectrum with lower amplitudes.
