Fairchild Semiconductor has introduced the primary-side regulated pulse width modulation controllers FAN100 and FSEZ1016A, which simplify design and reduce board space.
The FSEZ1016A integrates a EZSWITCHPSRPWM controller with a primary-side regulated PWM controller and a power MOSFET, while the FAN100 is a primary-side regulated PWM controller. Through this integration, these controllers use their built-in proprietary TRUECURRENT technology and tight pressure range for the most accurate constant flow control without the need for a secondary-side feedback circuit. Since the constant current over a wide voltage range is tightened, the same circuit can be used for a different number of strings of LEDs, increasing design flexibility, reducing time to market, and extending the life of HBLEDs. Thanks to the high degree of integration of these PSRPWM controllers, board space can be saved to match the trend of shrinking bulb dimensions.
The FSEZ1016A and FAN100 feature a proprietary power-saving mode that provides turn-off time modulation to linearly reduce the PWM frequency under light load conditions. In addition, they can minimize power consumption by reducing secondary-side feedback circuits and components (stand-by-load lighting, computing, industrial control, and home appliances, etc., power-sensitive Maximize energy savings in your application.
