AX2023-30V/1.5A High Brightness Step-Down

AX2023-30V/1.5A High Brightness Step-Down LED Drive DataSheet

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.
