This reference design drives the low-voltage brushless DC (BLDC) motor with universal AC power supply input. The design has an onboard, reinforced isolated AC/DC switch power supply to convert the AC main input to isolated low-voltage DC output. It also combines a fully-integrated and well-protected single-chip, sensorless, sinusoidal brushless motor controller for low-audible noise operation. The desin is optimized with very small form factor and high efficiency which could be easily fit into motor.
