New Reference Design Kit for a High Efficiency, High Power Factor, TRIAC Dimmable LED Driver

A newly released reference design kit for LinkSwitch-PH® (RDK-193) describes a high power-factor corrected dimmable LED driver designed to drive 21 V at 0.33 A from an input voltage range of 90 VAC to 265 VAC. The LED driver
utilizes the LNK403EG from Power Integrations.

Power Integrations Introduces Two New TRIAC-dimmable LED Driver ICs

Power Integrations has introduced LinkSwitch-PH and LinkSwitch-PL, two new families of TRIAC-dimmable, single-stage, power-factor-corrected LED driver ICs targeting solid-state lighting (SSL) applications. Both LinkSwitch-PH (optimized for isolated systems) and LinkSwitch-PL (optimized for non-isolated systems) deliver flicker-free monotonic TRIAC dimming and a user experience similar to that provided by incandescent illumination.

New 50 W Auxiliary/Standby Supply for Laser Printer

PI recently published a design example report (DER-245) for an auxiliary/standby supply for a laser printer.

Energy efficient features include:

  • Full load efficiency >82.5% (115 / 230 VAC)
  • Efficiency >78% above 1% load
  • Average efficiency >82% (25%, 50%, 75%, 100% load points)
  • No-load input power <130 mW (<100 mW achievable)
  • Simplifies meeting ENERGY STAR 2.0, 80 Plus and EuP requirements

To learn more, see DER-245.

New 65 W Power Supply Design for Notebook Adapters

PI recently published a new design report for notebook adapters using TOPSwitch®-JX. This new design is both highly energy efficient and very compact.

Features include:

  • Very low no-load input power: < 90 mW at 230 VAC
  • High full-load efficiency: > 86% at 90 VAC / 60Hz
  • High average efficiency: > 89.5%
  • 132 kHz operation reduces transformer size, reducing cost and improving efficiency
