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. 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 tracking the output voltage to an external source. This allows external sequencing of different supply rails and limits the inrush current during start-up.
The TPS62851xis available in an 8-pin 1.6-mm × 2.1-mm SOT583 package, offering a high power density solution.
