Industry's first LED driver design for 100W A19 incandescent bulbs

Key words: DER-322, LED driver, PI, incandescent March 20, 2012 hearing, the efficiency of the world's tallest, longest lasting off-line LED driver IC manufacturer Power IntegraTIons company, today announced the launch of a high-power LED bulb replacement for the application of LED driver reference design. The driver can provide the necessary replacement lamp power 100 W A19 incandescent bulbs LED, which is the industry's first such design. DER-322 introduce is a non-isolated, high efficiency (93%), high power factor (PF) LED driver, it can be 195 VAC to 265 VAC (47 Hz - 63 Hz) in the input voltage range of a rated voltage of 78 V to provide the LED string 230 mA drive. The LED driver using Power IntegraTIons company LinkSwitch ™ -PL series ultrathin IC device LNK460VG designed. DER-322 drive, which can fit into the A19 bulb, not only in EN61000-3-2 C (D) standard, also easily reach THD limit requirements. Its power factor (PF) value of more than 0.95, so both for commercial applications, but also for consumer applications. Since the PFC converter CC and integrated in the same switching stage, the number of elements of the design is very small, which contributes to miniaturization of the drive to reduce cost and enhance reliability. In addition, it eliminates the need for the short life of the input bulk electrolytic capacitor. 2012-3-23 20:44:48 Upload Download attachments (143.46 KB) DER-322 Andrew Smith Power IntegraTIons product marketing manager, said: "Efficiency DER-322 is 8-10% higher than the previous solution, the advantage is obvious, will be made in the design of a 100 W A19 incandescent commercially viable light bulb replacement breakthroughs. with the LED luminous efficiency rising, this important milestone will soon become a reality. At the same time, using the LinkSwitch-PL series IC also can easily produce a cost-effective 60 W and 75 W lamp bulb replacement. " DER-322 A19 although suitable for replacing incandescent light bulb LED lamp driver, but may also be configured to replace the LED lamp T8 lamp driver, therefore, both for the high-end LED lighting designer, or design cost optimization dedicated retail bulb division, it has a strong appeal. The reference design can be slightly modified to support a triac dimmer.
