This data brief introduces the characteristics of the STEVAL-ISA044V6 demonstration board, including input voltage range, maximum current, internal switching frequency, PWM mode operation, inhibit pin, quiescent current, etc.
The STEVAL-ISA044V6 is a demonstration board designed for evaluation purposes, featuring the ST1S10 step-down DC-DC converter in a DFN package. This device is optimized for powering high voltages in LCD applications and low voltages in digital-core HDD applications, replacing high-current linear solutions when power dissipation is a concern.
| Input voltage range | 2.5 V to 18.0 V |
|---|---|
| Max output current | 3A |
| Switching frequency | 900 kHz |
| Thermal shutdown temperature | 150 °C |
| Quiescent current (inhibit state) | < 6 µA |
It is a demonstration board based on the ST1S10 device assembled in a DFN package.
No, synchronous rectification removes the need for an external Schottky diode.
