TPSM8281x are a family of pin-to-pin, 1A, 2A, 3A, 4A, and 6A compatible 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. The devices are used in telecommunication, test and measurement, and medical applications with high power density and ease of use requirements. Low resistance switches allow up to 6A continuous output current at high ambient temperatures. 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. In power save mode, the TPSM8281x automatically enters PFM at light loads to maintain high efficiency across the whole load range. The TPSM8281x provides a 1% output 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 action allows external sequencing of different supply rails and limits the inrush current during start-up.
