Power Integrations' LYTSwitch-4 LED driver IC product family adds new voltage devices

SAN JOSE, USA: High efficiency, high reliability LED driver IC world leader in the field of Power Integrations Corp, launched a series of new devices for high pressure applications, On the occasion, LYTSwitch-4 LED driver IC products have been readily available.

LYTSwitch-4 IC bulbs and tubes can be applied as well as mining lamp lighting provides accurate output current and high efficiency. The device not only can simplify design, reduce costs, while ensuring a consistent illumination lamp light output and triac dimming applications provide excellent performance.

LYTSwitch-4 IC using PFC and CC combined single-stage converter topology, so in a typical application power factor over 0.95, more than 90 percentage efficiency.

Based on the new drive is designed to easily meet EN61000-3-2C THD standards, the design has been optimized to provide less than 10 percentage THD.

The load range and production environments, regulation better than + / - 5 percentage, thereby reducing the need for over designed, easy to meet minimum brightness target, thereby reducing system cost.

Device has a high switching frequency, so you can use in your design smaller, lower cost core, and the frequency dithering technique can also reduce EMI filtering requirements. These factors combine to make the LED driver design fits easily into space constrained bulb.

Power Integrations Andrew Smith, senior product marketing manager, said; "As LYTSwitch-4 LED driver IC combines high efficiency and excellent dimming performance, so the initial low-voltage devices since its inception, the series has been popular IC even with cutting edge and trailing edge TRIAC dimmers use and a lower conduction angle, power supply design can still meet NEMA SSL-7 standard boot drive very fast, usually less than 500 milliseconds, even less than in the open 10 percentage of the amount of light output which is also fast launch speed, and virtually eliminates the phenomenon suddenly brighter. "

Designers can use our recently developed jointly with Cree high voltage LED lighting reference designs to evaluate the latest LYTSwitch-4 LED driver IC products. DER-396 introduce is a PAR38 spot light LED driver design. These documents and all other similar co-developed with Cree reference designs

Use LYTSwitch IC can be designed smaller, longer lamp life, and its scope is very broad, including consumer bulbs, commercial lighting and T8 lamps, industrial lighting, mining lamps and outdoor lighting. LYTSwitch devices can also provide Power Integrations products with all the usual safety features, including overvoltage, overcurrent and overheat protection.

In addition, LYTSwitch devices without using an optocoupler or bulk electrolytic capacitor, thus reducing component count and improve reliability. High LYTSwitch-4 IC now eSIP-7C and eSIP-7F package to provide samples for 10,000-piece quantities is priced at $ 0.58 per piece to $ 0.62.
