ST1S12G18R General Description
While traditional high current linear solutions can be effective in certain applications, they often result in significant heating issues that can compromise system reliability. In contrast, the ST1S12G18R DC-DC converter offers a more efficient and reliable alternative by leveraging its step-down design and high switching frequency of 1.7 MHz. This conversion allows for up to 0.7A of output current over an input voltage range of 2.5V to 5.5V, making it an attractive solution for demanding applications such as HDD power supply. Additionally, the device's thermal protection and current limiting features ensure reliable operation even in the event of accidental short-circuit events
Features
- Compact and reliable design
- Low power consumption
- Suitable for mobile devices
