On April 16, 2015, Datongda Holdings, a leading electronic component distributor dedicated to the Asia-Pacific market, announced that its product has launched a commercial lighting solution based on the Infineon quasi-resonant controller ICL5101 to meet commercial lighting applications. The need for high performance, high reliability systems. Typical applications include indoor and outdoor LED lighting, high/low shed lighting, street lighting, parking and ceiling lighting, office lighting, retail and store lighting.
Infineon ICL5101 integrates PFC and LLC into the company, which reduces the cost and reduces the size and system reliability Operating parameters can be adjusted by simple resistors; can be lit in any very short time (less than 200 ms); its adjustable PFC unit can output high quality power, with a true THD of less than 10% over a wide input voltage range. To help lighting manufacturers achieve energy efficiency standards; their junction temperature range is -40 ° C to +125 ° C; external over temperature protection and capacitive load protection and other protection functions to ensure timely detection of fault conditions and improve system safety . It is worth emphasizing that the resonant topology efficiency supported by the ICL5101 is as high as 95%.

Litecoin (LTC) is a cryptocurrency created as a fork of Bitcoin in 2011. It uses a hashing algorithm called Scrypt that requires specifically designed mining software and hardware. It is minable, and continues to rank in the top cryptocurrencies for value and trading volume.
Litecoin mining is the process of validating transactions in the blockchain, closing the block, and opening a new one. Litecoin uses the proof-of-work consensus mechanism, which uses computational power to solve the nonce, which is part of the hash, that secures the block. The hash is the alphanumeric sequence of numbers that is encrypted by the hashing algorithm. When the nonce is solved, Litecoin is rewarded.
Litecoin mining became popular in 2011 when Charlie Lee, a software engineer at Google, announced its creation as a Bitcoin fork with modifications intended to help it scale more effectively.
Just like Bitcoin, it can be mined on computers using central processing units and graphics processing units. However, it isn't as profitable or competitive as purchasing an application-specific integrated circuit (ASIC) and joining a mining pool.
