3 Description
The TPS62850x-Q1 is a family of pin-to-pin 1-A, 2-
A (continuous), and 3-A (peak) high efficiency, easyto-
use synchronous step-down DC/DC converters.
These devices are based on a peak current mode
control topology. These devices are designed for
automotive applications such as infotainment and
advanced driver assistance systems. Low resistive
switches allow up to 2-A continuous output current
and 3-A peak current. In the TPS62850x-Q1, the
switching frequency is externally adjustable from 1.8
MHz to 4 MHz. The devices can also be synchronized
to an external clock in the same frequency range.
In PWM/PFM mode, the devices automatically enter
power save mode at light loads to maintain high
efficiency across the whole load range. The family
provides a 1 output voltage accuracy in PWM mode
which helps design a power supply with high output
voltage accuracy.
The TPS62850x-Q1 are available in a SOT583
package.
