Description

• Parameters: NON-ISOLATED LED LIGHTING DRIVE IC WITH BUILT-IN HIGH-VOLTAGE MOSFET AND HIGH CONSTANT CURRENT ACCURACY
• Description: 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
• Features: Proprietary constant control method (Patent) Boundary-Conduction mode The patented closed-loop control technology eliminates the need for external compensation networks, providing moisture and leak protection LED short circuit protection LED open circuit protection VCC undervoltage protection The VCC clamping tube is internally integrated Over temperature protection Over current protection Internal current reduction in high temperature condition
• Applications: Amplifier, LED Lighting, Lighting
