The TPS62850x-Q1 is a family of pin-to-pin 1A, 2A (continuous), and 3A (peak) high efficiency, easy-to-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 a SOT583 package.
