AX2024-Step-Down WLED-Current Controller with Wide 6V to 60V Input Voltage DataSheet
The AX2024 is a high-efficiency step-down controller. It is designed to operate in
continuous current mode (CCM) to power LEDs of high-brightness with a wide input voltagerange of 6V to 60V.
The AX2024 employs a hysteretic control architecture that accurately regulates LEDcurrent with a feedback coming from an external high-side current-sense resistor. This control scheme optimizes circuit stabilization and fast response time without loop compensation. Its low 200mV average feedback voltage reduces power loss and improves the converter’s efficiency.
The AX2024 implements PWM and analog dimming together through the EN/DIM pin.
The AX2024 includes thermal overload protection in case of output overload.
The AX2024 is available in TSOT-23-6L package.
