In order to meet the critical needs of the high-brightness LED market, Fairchild Semiconductor has introduced the primary-side regulated pulse width modulation controllers FAN100 and FSEZ1016A, which simplify design, reduce board space, and provide important Performance advantage. The FSEZ1016A is an EZSWITCH PSRPWM controller that integrates 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 achieve the most accurate constant current control with their built-in proprietary TRUECURRENT technology and tight pressure range 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. Because of the high degree of integration of these PSRPWM controllers, board space can be saved to match the trend of shrinking bulb sizes.
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 the secondary side feedback circuits and components (standby power <0.15W without load). All of these energy-saving features are essential to enable power supplies to meet stringent energy efficiency regulations. In addition, these PSRPWM controllers provide robust protection features such as undervoltage lockout (UVLO), overvoltage protection (OVP), and overtemperature protection (OTP).
Fairchild's PSRPWM controllers enhance their broad portfolio of power-efficient electronics for power-sensitive applications such as power adapters, power supplies, lighting, computing, industrial control and home appliances. Maximize energy savings.
