Description

The ACE7360X 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 voltage range of 6V to 60V.

The ACE7360X employs a hysteretic control architecture that accurately regulates LED current 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 ACE7360X implements PWM and

analog dimming together through the EN/DIM pin.

The ACE7360X includes thermal overload protection in case of output overload.

The ACE7360X is available in SOT23-6 package.
