Description
The LT8301 integrates a 240mA, 150V power switch, allowing it to deliver output power up to 6W depending on the application and transformer choice. It utilizes boundary mode operation, which offers high efficiency and low output ripple. The primary side winding senses the output voltage, and the device maintains regulation through a unique feedback mechanism without additional components on the secondary side.
Packaged in a small SOT-23 form factor, the LT8301 is designed for compact and efficient power supply designs, with features like soft-start, adjustable current limit, and undervoltage lockout. Its simplicity, efficiency, and integration make it ideal for space-constrained applications.
