1.4 Device Information

The purpose of TPSM86837EVM is to showcase the typical application of the TPSM86837 device. With the wide operating input voltage range of 4.5V to 28V, the TPSM86837 is designed for systems powered from 12V, 19V, 24V power-bus rails. The device supports up to 8A continuous output current. The output voltage range is from 0.6V to 5.5V. The TPSM86837 device provides 800kHz and 1.2MHz switching frequencies for selection. D-CAP3™ control mode provides an easy-to-design, stable regulation with very little external components, and supports cost-effective ceramic capacitors. TPSM86837 operates in Eco-mode™ (auto-skip mode) to attain high efficiency at light load.

Table 2-2 shows the rated input voltage and output current ranges for the evaluation module.
