3 Description
The TPS6281x-Q1 is family of pin-to-pin 1-A, 2-
A, 3-A, and 4-A synchronous step-down DC/DC
converters. All devices offer high efficiency and ease
of use. The TPS6281x-Q1 family is based on a
peak current mode control topology. The TPS6281x-
Q1 is designed for automotive applications such as
infotainment and advanced driver assistance systems.
Low resistive switches allow up to 4-A continuous
output current at high ambient temperature. The
switching frequency is externally adjustable from 1.8
MHz to 4 MHz and can also be synchronized to
an external clock in the same frequency range. In
PWM/PFM mode, the TPS6281x-Q1 automatically
enter power save mode at light loads to maintain
high efficiency across the whole load range. The
TPS6281x-Q1 provide 1 output voltage accuracy in
PWM mode which helps design a power supply with
high output voltage accuracy. The SS/TR pin allows
setting the start-up time or forming tracking of the
output voltage to an external source. This feature
allows external sequencing of different supply rails
and limiting the inrush current during start-up.
The TPS6281x-Q1 is available in a 3-mm × 2-mm
VQFN package with wettable flanks.
