Motor control applications require power supply devices to provide bias, voltage and current, to control devices such as the Fairchild BLDC/PMSM Controller, MCUs (microcontrollers), FPGAs (Field Programmable Gate Arrays), and DSPs (Digital Signal Processors).
Primary-Side Regulated (PSR) CV/CC Controllers with Integrated MOSFET, (SMPS): FSEZ13x7
Fairchild Semiconductor offers a wide range of PSR controllers with and without integrated MOSFET. Here we feature the FSEZ1317A.
This is just one example of PSR offerings from Fairchild Semiconductor.
FSEZ1317A Features:
Patented PSR technique: EZ-PSR and PWM controller for Constant Voltage (CV) and Constant Current (CC) control without secondary-side feedback circuitry.
Cost-effective solution: High integration.
Highly rugged 700V MOSFET.
