The SX1308 is a highly efficient, constant-frequency, current-mode step-up converter designed for small, low-power applications. Housed in a compact 6-pin SOT-23 package, it operates with an input voltage range of 2V to 24V, making it versatile for various power supply applications. The converter features a 1.2MHz fixed switching frequency, allowing the use of tiny, low-cost capacitors and inductors, which makes it an excellent choice for space-constrained designs.

The SX1308 integrates a powerful internal switch with a current limit of 4A, capable of delivering an output voltage of up to 28V. Its internal compensation mechanism ensures stability and efficient regulation of the output voltage, which can be adjusted to meet specific requirements. The device also offers automatic Pulse Frequency Modulation (PFM) mode during light loads, improving efficiency by reducing switching frequency and extending battery life.

Built-in protection features include under-voltage lockout, current limiting, and thermal overload protection, safeguarding the circuit against potential damage caused by overloads. The SX1308 achieves up to 96% efficiency, making it an ideal choice for battery-powered devices. With its compact size, high efficiency, and integrated safety mechanisms, the SX1308 is suitable for a wide range of applications, including mobile devices, wearables, and other low-power electronics.
