AX2023-30V/1.5A High Brightness Step-Down LED Drive
General Description - The AX2023 is a high-efficiency step-down LED driver controller with a wide input voltage range of 6V to 30V. - The AX2023 employs a continuous conduction mode architecture that accurately regulates LED current with a feedback coming from an external current-sense resistor. This control scheme optimizes circuit stabilization and fast response time without loop compensation. Its low 100mV average feedback voltage reduces power loss and improves the converter’s efficiency. - The AX2023 implements PWM and analog dimming together through the DIM pin. - The AX2023 is also Includes thermal regulation protection in case of output overload. - The AX2023 is available in SOT-23-5L package.
Features - Wide 6V to 30V Input Range - Able to Drive ≤1.5A LED Load - ±3% output current accuracy - Up to 1MHz switching frequency - High Efficiency - Analog and PWM Dimming - Open LED Protection - No need compensation - Thermal Regulation - RoHS and Halogen free compliance. - Available in SOT23-5 Package
Applications - Low Voltage Halogen Replacement - DC/DC or AC/DC LED Driver Application - Automotive/Decorative LED Lighting - Emergency Lighting - LED Backlighting
