SD693XAS
NON-ISOLATED LED LIGHTING DRIVE IC WITH BUILT-IN HIGH-VOLTAGE MOSFET AND HIGH CONSTANT CURRENT ACCURACY

    SD693XAS is designed for non-isolated LED driving, with a floating ground Buck architecture for peripheral application and an integrated high-voltage power MOSFET. With this structure, current is sensed and closed-loop is formed with the internal error amplifier for high constant current accuracy and high input/output regulation rate. Boundary Conduction mode is adopted for decreasing switching loss and improving the conversion efficiency.

    SD693XAS integrates various protections, such as output open circuit protection, output short circuit protection, cycle-by-cycle over current protection, and over temperature protection.

    SD693XAS integrates a VCC regulator, enabling peripheral operation without the need for auxiliary windings and maximizing the output voltage range.
