SLUS964D – NOVEMBER 2009 – REVISED MARCH 2018 TPS4030x 3-V to 20-V Input, Voltage Mode, Synchronous Buck Controller
1 Features 3 Description 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. 1 Input Voltage Range From 3 V to 20 V
300-kHz (TPS40303), 600-kHz (TPS40304), and
1.2-MHz (TPS40305) Switching Frequencies
