DescriptionThe TPS4030x is a family of cost-optimized
synchronous buck controllers that operate from 3-Vto
20-V input. The controller implementsa voltage-mode
control architecture with input-voltage feed-forward
compensation that responds instantlytoa changein
input voltage. The switching frequencyis fixedat
300 kHz, 600 kHz,or 1.2 MHz.
The frequency spread-spectrum (FSS) feature adds the switching frequency, significantly reducing the
peak EMI noise and makingit much easierto comply
with EMI standards.
The TPS4030x offers design witha varietyof user-
programmable functions, including soft start,
overcurrent protection (OCP) levels, and loop
compensation.
OCP level may be programmedbya single external
resistor connected from the LDRV pin to circuit
ground. During initial power on, the TPS4030x enters calibration cycle, measures the voltageat the LDRV
pin, and sets an internal OCP voltage level. During
operation, the programmed OCP voltage levelis
comparedto the voltage drop across the low-side
FET whenitis onto determine whether thereis an
overcurrent condition. The TPS4030x then entersa
shutdown and restart cycle until the faultis removed.
