【Application】

These PSR PWM controllers enhance Fairchild’s extensive power offerings to enable energy-efficient electronics. These products maximize energy savings in power-sensitive applications such as power adapters, power supplies, lighting applications, computers, industrial controls and home appliances.

【Overview】

Fairchild Semiconductor addresses a critical need in the high brightness (HB) light emitting diodes (LED) market with its primary side regulation (PSR) pulse-width modulation (PWM) controllers that simplify design, reduce board space and provide important performance advantages. The FSEZ1016A is an EZSWITCH™ that integrates a PSR PWM controller with a power MOSFET and the FAN100 is a PSR PWM controller. Through this integration, these controllers achieve the most accurate constant current (CC) through their built-in proprietary TRUECURRENT™ technology and tight constant voltage (CV) without using secondary-side feedback circuitry. By tightening the constant current over a wide voltage range, the same circuit can accommodate different numbers of LED units in a string, increasing design flexibility, accelerating time-to-market and stretching the lifetime of HB LEDs. With this high level of integration, these PSR PWM controllers conserve board space, accommodating the form factor of lamp cases that continue to diminish in size.
The FSEZ1016A and FAN100 feature a proprietary green-mode function that provides off-time modulation to linearly decrease the PWM frequency under light-load conditions. They also minimize power consumption (standby power at no load condition <0.15W) by reducing the secondary-side feedback circuitry and components. All of these power-saving features are integral in enabling power supplies to meet stringent energy efficiency specifications. In addition, these PSR PWM controllers offer robust protection features such as under-voltage lockout (UVLO), over voltage protection (OVP) and over temperature protection (OTP).
