Solutions Help Designers Meet Standby Power and Regulatory Specifications
Thu, 04/08/2010 - 1:18pm
Fairchild Semiconductor offers designers of mobile chargers, adapters and LED lighting applications multiple solutions to meet the stringent power and regulatory specifications such as ENERGY STAR® Level V. In charger and adapter applications, designers have been challenged to lower standby power and achieve higher efficiency, all while reducing the form factor of their designs. With a broad portfolio of PSR PWM controllers, including the FSEZ1307 PSR controller with high voltage (HV) startup and an integrated MOSFET, Fairchild devices simplify designs, save board space and meet today's demands for power savings. Key features available in the Fairchild portfolio are 30 mW standby power, HV start up and an integrated power MOSFET for ease of design, primary side regulation without secondary side feedback and a universal AC input range. Unlike competitive solutions, Fairchild's PSR PWM controllers achieve constant voltage (CV) (±5%), constant current (CC) (±7%), 30 mW standby power and ENERGY STAR Level V efficiency. For LED lighting applications, Fairchild's PSR PWM controllers achieve a very accurate CC through built-in, proprietary TRUECURRENT technology and tight CV without secondary-side feedback circuitry.
