TPSM82851x is a family of pin-to-pin compatible, 0.5-A, 1-A, and 2-A high-efficiency and easy to use synchronous step-down DC/DC power modules with integrated inductors. The devices are based on a fixed-frequency peak current-mode control topology and they can be used in telecommunication, test and measurement, and medical applications with high power density and ease of use requirements. Low resistance switches allow up to 2-A continuous output current at high ambient temperatures. 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 PFM/PWM mode, the TPSM82851x automatically enters power save mode at light loads to maintain high efficiency across the whole load range. The TPSM82851x provides a 1% feedback voltage accuracy in PWM mode which helps design a power supply with high output voltage accuracy. The SS/TR pin sets the start-up time or tracks the output voltage to an external source. This feature allows external sequencing of different supply rails and limits the inrush current during start-up.
