ST1S03PUR General Description

Offering advanced functionality in a compact package, the ST1S03PUR is a state-of-the-art step-down DC-DC converter tailor-made for powering low voltage digital cores in HDD applications and other similar scenarios. By replacing conventional high current linear solutions, this converter efficiently manages power dissipation to prevent overheating in the operating environment. With a generous input voltage range of 3V to 16V, the ST1S03PUR can deliver a maximum current of 1.5A. Its high switching frequency of 1.5 MHz enables the use of small surface-mount components, such as an inductor, a Schottky diode, and two capacitors, along with a simple resistor divider for setting the output voltage. Using a current mode PWM topology and low ESR SMD ceramic capacitors, this converter ensures minimal output ripple for enhanced performance. Equipped with thermal protection and current limitation features, the ST1S03PUR offers reliable safeguards against short-circuit events. Encased in a DFN6D package, this converter represents an efficient and dependable solution for critical power management tasks
