The TPS62850x is a family of pin-to-pin 1-A, 2-A (continuous), and 3-A (peak) 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 and 3-A peak current. 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 and PFM mode, the TPS62850x automatically enters power save mode at light loads to maintain high efficiency across the whole load range. The TPS62850x provides a 1% output voltage accuracy in PWM mode, which helps design a power supply with high output voltage accuracy, fulfilling tight supply voltage requirements of digital processors and FPGA.

The TPS62850x is available in an 8-pin 1.60-mm × 2.10-mm SOT583 package.
