Description for the TPS628510

The TPS62851x is a family of pin-to-pin 0.5-A, 1-A, and 2-A high efficiency, easy-to-use, synchronous step-down DC/DC converters. They are based on a peak current mode control topology. Low resistive switches allow up to 2-A continuous output current at high ambient temperature. The switching frequency is internally fixed at 2.25 MHz and can also be synchronized to an external clock in the range from 1.8 MHz to 4 MHz. In PWM/PFM mode, the TPS62851x automatically enters Power Save Mode at light loads to maintain high efficiency across the whole load range. The TPS62851x provide a 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 allows external sequencing of different supply rails and limits the inrush current during start-up.

The TPS62851xare available in a SOT583 package.
