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. 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 allows external sequencing of different supply
rails and limiting the inrush current during start-up.
The TPS6281x-Q1 is available in a 3-mm x 2-mm
VQFN package with wettable flanks.
