The TPS6281x-Q1 is family of pin-to-pin 1-A, 2-A, 3-A and 4-A synchronous step-downDC/DC converters. All devices offer high efficiency and ease of use. The TPS6281x-Q1 family isbased on a peak current mode control topology. TPS6281x-Q1 is designed for automotive applicationssuch as Infotainment and advanced driver assistance systems. Low resistive switches allow up to 4-Acontinuous output current at high ambient temperature. The switching frequency is externallyadjustable from 1.8 MHz to 4 MHz and can also be synchronized to an external clock in the samefrequency range. In PWM/PFM mode, the TPS6281x-Q1 automatically enter Power Save Mode at lightloads to maintain high efficiency across the whole load range. The TPS6281x-Q1 provide 1% outputvoltage 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 anexternal source. This allows external sequencing of different supply rails and limiting the inrushcurrent during start-up.

The TPS6281x-Q1 is available in a 3-mm x 2-mm VQFN package with wettable flanks.
