具备可调光和PFC(功率因素校正)特性,能够精确控制并且具有高效、小体积和高可靠性,这些是目前LED照明驱动芯片需要面对的要求。针对这一需求,Power Integrations公司(PI)日前推出了两款支持TRIAC调光的单级PFCLED驱动器,其中,LinkSwitch-PH适合设计隔离式电源,LinkSwitch-PL适合设计非隔离式电源。
With dimming and PFC (power factor correction) characteristics, can be precisely controlled and has high efficiency, small size and high reliability, which is the current LED lighting driver chip needs to be faced. To meet this demand, Power Integrations Inc. (PI) has introduced two TRIAC dimming single-stage PFCLED drivers. Among them, LinkSwitch-PH is suitable for designing isolated power supplies, and LinkSwitch-PL is suitable for designing non-isolated power supplies.
