The AW36612A is a LED driver that designs with current mode. The AW36612A utilizes a 1.5MHz frequency synchronous buck converter to provide power to the 1.2A peak constant current LED sources. The device also provides hardware RUN pin to realize PWM to Analog dimming function. Input voltage from 2.7V to 5.5V makes the AW36612A ideally suited for single Li-Lon battery powered applications.
The device operates over a -40°C to +85°C ambient temperature range. The fault protection includes OCP function which ensure the peak of inductor current is less than 1.7A.The use of synchronous switches instead of external Schottky diode improves the efficiency.
The AW36612A is available in DFN 2mm×2mm×0.75mm -6L package.
