WPG Holdings Pinjia launch vehicle power LED based on Infineon TLD5098EL dimming scheme can drive

In March 11, 2014, committed to the Asia Pacific market leading electronic components distributor --- WPG holdings announced that its Pinjia launch vehicle power LED based on Infineon TLD5098EL dimming scheme can drive the short-circuit protection function with built-in ultra flexible DC / DC boost controller IC tailored for automotive LED applications. Its main function is to increase (increase) or decrease (decrease) the output voltage to maintain a constant LED current.

TLD5098EL can be applied to boost ground (B2G), boost battery (buck boost) and SEPIC configuration, can make the voltage up to 60V. Analog dimming function can be used to adjust the LED average current, calibrate the brightness of the LED or play a role in thermal stress protection. The external control concept of TLD5098EL consists of two external MOSFET, which can be optimized for the desired forward current (MOSFET).

About the United Nations General Assembly holdings:

WPG holdings is the Asia Pacific market share leading electronic components distributor, headquartered in Taipei (TSE:3702), which owns the world group, Pinjia group, Ding Quan Group and Youshang group, the number of employees nearly 6000 people, more than 250 products suppliers, more than 130 global distribution stronghold (Asia Pacific region about 80), 2013 sales amounted to $13 billion 600 million (Unaudited).

WPG holdings to create industrial holdings platform, continued to optimize the front marketing and logistics support team, to play professional industry supply chain partners, create demand (Demand Creation) provides turnkey solutions (Turnkey, Solution), technical support, warehousing logistics and IC e-commerce and other value-added services to meet the original equipment manufacturer (OEM), the original design manufacturer (ODM), electronic manufacturing service providers (EMS) and small and medium-sized enterprises in different customer needs. The internationalization and localization of the scale of sales channels, long-term roots in the Asia Pacific market, successive years of professional media named "Asia's best IC distributor" Ju Wen third global electronic components distributor.

In order to improve the localization of WPG service quality, to meet the needs of different service area Chinese customers, WPG (China) six field service including Chinese (China Based Manufacturers), Taiwan (Taiwan-Based Manufacturers) (Electronic Manufacturing Service), foreign and Japanese (Japan-Based Manufacturers) and Han (Korea-Based Manufacturers) and business Hong Kong (HongKong-Based Manufacturers) customer. In addition to providing the best turnkey solutions (Turnkey Solution), and in order to meet customer demand for small quantities of device procurement, in particular the establishment of a dedicated small batch service team (SQS, Small Quantity). WPG respectively in the mainland and Hongkong established WPG trade, WPG Trading (Shenzhen) and WPG Electronics (Hongkong), the industry benchmark for enterprise ". The preferred pathway of vision, the full implementation of" core team, integrity, professional, efficiency "values, to professional services, suppliers, and customers shareholders of mutual benefit and win-win.
