SX1308 Step-Up Converter IC | 1.2MHz Boost Converter 2A – SOT23-6

The SX1308 is a high-efficiency 1.2MHz step-up (boost) DC-DC converter IC designed for compact, low-power applications requiring reliable voltage boosting. With an integrated 80mΩ power MOSFET and up to 96% efficiency, it provides exceptional performance in battery-powered and portable electronics.

Accepting input voltages from 2V to 24V and delivering output voltages up to 28V, the SX1308 supports a wide range of power conversion requirements. Its high switching frequency enables the use of small inductors and capacitors, reducing overall design size. The IC also includes internal soft-start, current limiting, thermal shutdown, and undervoltage lockout, ensuring robust and safe operation in demanding environments.

At light loads, the SX1308 automatically shifts to pulse frequency modulation (PFM) to improve efficiency and extend battery life. Its compact SOT23-6 package makes it suitable for LED drivers, power banks, battery-powered devices, sensors, and low-voltage step-up applications.
