Overview of TPS628112MQWRWYRQ1

Automotive electronics applications such as infotainment and advanced driver assistance systems require robust and efficient power management solutions, and the TPS6281x-Q1 family of synchronous step-down DC/DC converters delivers on those requirements. Offering a range of 1A to 4A continuous output current, these converters are designed to operate at high ambient temperatures, thanks to their low resistive switches. The peak current mode control topology ensures high efficiency and ease of use, while the externally adjustable switching frequency and PWM/PFM mode enable power-saving features at light loads, maintaining high efficiency across the load range. Moreover, the TPS6281x-Q1 family provides 1% output voltage accuracy in PWM mode, allowing for precise power supply design, while the SS/TR pin allows for flexibility in setting start-up times and tracking output voltage externally. Packaged in a compact 3mm x 2mm VQFN package with wettable flanks, these converters offer reliable and space-efficient power management solutions for automotive applications
