TPSM8281x is a family of pin-to-pin compatible, high-efficiency, and easy to use synchronous step-down DC/DC power modules with integrated inductors with output currents ranging from 1A up to 4A. The devices use a fixed-frequency peak current-mode control topology and support high power density requirements for telecommunication, test and measurement, and medical applications. Low resistance switches allow up to 4A continuous output current at high ambient temperatures. The switching frequency is adjustable from 1.8MHz to 4MHz and can also be synchronized to an external clock. In PFM/PWM mode, the TPSM8281x maintains high efficiency over the whole load range. The devices provide 1% output voltage accuracy in PWM mode, which eases designing precise power supplies. The SS/TR pin can be used to limit inrush current through a precise start-up ramp, or for sequencing by tracking the output voltage to an external voltage applied to this pin.
