Integrated 30-W Sensorless BLDC Motor Drive Retrofit Reference Design with 90- to 265-V AC Input
Description
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.
Features
- Reinforced isolated flyback AC/DC power supply providing 24-V/36-W outputVery low-standby power below 50 mW and high-efficiency AC/DC power supply giving a full load efficiency of 86%Highly integrated and protected single-chip: sinusoidal brushless motor controller reduces external parts count eliminating the programming overhead of motor controlSmall PCB form factor of Ø64 mmFully protected system with short circuit: over current: blocked rotor protection
