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. The 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 feature allows external sequencing of different supply rails and limiting the inrush current during start-up.

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