The TPSM656x0 is a family of 3A, 2A, 1A, 65V (70V tolerant) input synchronous step-down DC/DC power module that combines power MOSFETs, integrated inductor, and passives in a compact and easy-to-use 5.8mm × 5.2mm × 2.93mm, 19-pin enhanced HotRod QFN package. With the pin-selectable fixed-output voltages of 3.3V and 5V and adjustable output voltage from 1V to 24V, the TPSM656x0 is designed to quickly and easily implement a low-EMI design in a small PCB footprint. The module only requires the input and output filter capacitors to finish the design and eliminates the magnetics and compensation part selection from the design process. A pin-selectable ±5% or ±10% dual-random spread spectrum (DRSS) significantly reduces peak emissions through a combination of triangular and pseudo-random modulation while keeping output voltage ripple very low.
