The STEVAL-ISA044V5 is a demonstration board based on the ST1S10 device assembled in a Power SO-8 ePad package. The ST1S10 is a step-down DC-DC converter with the inhibit function optimized for powering high voltages in LCD applications and low voltages in digital-core HDD applications. It replaces the high-current linear solution when high power dissipation is an issue. It provides up to 3 A over an input voltage range of 2.5 V to 18.0 V, and synchronous rectification removes the need for an external Schottky diode. A high internal switching frequency (900 kHz) allows for the use of tiny surface-mount components, as well as a resistor divider to set the output voltage value. Only an inductor and 3 capacitors are required. The current-mode PWM architecture and stable operation with low-ESR SMD ceramic capacitors result in low output ripple. To maximize power conversion efficiency in light load, the regulator can work in burst mode automatically.
