The TPS6281x-EP is family of pin-to-pin, 1A, 2A, 3A, and 4A synchronous step-down DC/DC converters. All devices offer high efficiency and ease of use. The family of devices is based on a peak current mode control topology. Low-resistive switches allow up to 4A continuous output current at high ambient temperature. The switching frequency is externally adjustable from 1.8MHz to 4MHz and can also be synchronized to an external clock in the same frequency range. The device can automatically enter power save mode (PSM) at light loads to maintain high efficiency across the whole load range. The device provides 1% output voltage accuracy in PWM mode which helps design a power supply with high output voltage accuracy. The SS/TR pin allows the user to set the start-up time or form tracking of the output voltage to an external source, allowing external sequencing of different supply rails and limiting the inrush current during start-up.

The TPS6281x-EP device is available in a 2mm × 3mm, VQFN package.
