3 Description
The TPS62850x-Q1 is a family of pin-to-pin 1A,
2A (continuous), and 3A (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 2A continuous output current and
3A peak current. In the TPS62850x-Q1, the switching
frequency is externally adjustable from 1.8MHz to
4MHz. 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 an SOT583
package.
