Fairchild Semiconductor’s Primary Side Regulation PWM Controllers Simplify Design in High Brightness LEDs
Typical application schematic with FAN100
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.
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.
