Diodes Incorporated Introduces High-Efficiency, Single-Winding Inductor 500V Buck Led Drivers
Aug 19 15
Diodes Incorporated introduced the AL1678 family of LED Drivers. These devices are well-suited for driving non-dimmable retrofit LED bulbs in general illumination applications that do not require high power factor (>0.7). Ensuring a low total circuit bill-of-material (BOM) cost while keeping performance high, these 500V buck-converter LED drivers support output powers up to 15W for wide-ranging LED lighting applications such as Class-A/B/P and GU10 lamps across all mains line voltages. The AL1678 family is offered in the space-saving SO-7 and provides a variety of different current-rated 500V MOSFETs, which allow designers to select the most appropriate driver to meet the needs of different bulb wattage and cost requirements. With its improved driver topology, the AL1678 family provides significant circuit flexibility and delivers accurate constant current line and load regulation over the 85VAC to 277VAC universal input range. In addition, by operating in boundary-conduction mode, the driver keeps EMI low with greater than 90% high-efficiency, which aids with EMC compliance. The AL1678 LED drivers’ total BOM lamp cost is low because it removes the need for an external high-voltage MOSFET and an auxiliary winding, while requiring only a single external inductor. Integrated protection features include under-voltage lockout, over-temperature protection, LED open- and short-circuit protection, as well as a thermal fold-back function to help improve the system reliability of retrofit LED lamps at high temperature. The AL1678’s SO-7 package also helps improve electrical isolation and offers improved moisture resistance.
Diodes Incorporated Introduces DSR8F600
Aug 11 15
Diodes Incorporated introduced the DSR8F600. This 600V 8A hyper-fast rectifier has been designed specifically for use as a boost diode for power-factor correction (PFC) and continuous conduction mode (CCM) applications. The target market is in switched-mode power supplies (SMPS) that need to deliver a high output, greater than 75W, in end-equipment such as flat-panel TVs, servers and telecoms systems, where new regulatory standards in Europe, the USA, Japan and China require improved energy efficiency. A hyper-fast 20ns reverse-recovery time reduces PFC MOSFET switching losses, increases switching speed and improves energy efficiency, while a very fast soft recovery capability ensures ringing and EMI interference are reduced. Boost diode recovery losses are minimized by a low 3.9A reverse-recovery current, which also reduces power dissipation in the MOSFET and lowers the risk of system failure. A low 1.95V forward voltage drop also minimizes boost diode conduction losses. Aimed at designers of PFC circuits who need to achieve the lowest possible energy losses, the DSR8F600 provides best-in-class performance, generating the least noise and achieving the high power efficiency. The DSR8F600 is the first of a family of hyper-fast rectifiers; future introductions will provide even higher voltages and currents.

Diluted earnings per share attributable to common stockholders was $0.31 compared to $0.36 a year ago. EBITDA (non- GAAP) was $40,188,000 compared to $342,910,000 a year ago. Non-GAAP adjusted net income was $16.6 million, or $0.34 per diluted share, compared to $12.7 million, or $0.26 per diluted share, in first quarter 2015 and $18.2 million, or $0.38 per diluted share, in second quarter 2014. Net cash provided by operating activities was $33.9 million for the second quarter of 2014. Free cash flow was $22.1 million, which included $11.9 million of capital expenditures.
For the six months, the company's net sales were $425,634,000 compared to $433,203,000 a year ago. Income from operations was $38,901,000 compared to $37,486,000 a year ago. Income before income taxes and non controlling interest was $37,220,000 compared to $36,495,000 a year ago. Net income was $27,634,000 compared to $28,297,000 a year ago. Net income attributable to common stockholders was $26,210,000 compared to $27,587,000 a year ago. Diluted earnings per share attributable to common stockholders was $0.53 compared to $0.57 a year ago. EBITDA (non- GAAP) was $75,445,000 compared to $75,699,000 a year ago. Adjusted net earnings (non- GAAP) was $29,301,000 compared to $30,562,000 a year ago. Adjusted earnings per share (non- GAAP) - diluted was $0.60 compared to $0.63 a year ago.
For the third quarter of 2015, the company expects revenue to range between $209 million and $225 million, or a decrease of 4.8% to an increase of 2.5% sequentially. At the midpoint of the guidance, total revenue is projected down 1% from the second quarter due to a significant reduction in the revenue associated with assembly test manufacturing services; revenue excluding manufacturing services is projected to grow approximately 3% sequentially. The company expects gross margin to be 31.5%, plus or minus 2%. Operating expenses are expected to be approximately 22.2% of revenue, plus or minus 1%. The company expects its income tax rate to be 26%, plus or minus 3%, and shares used to calculate diluted EPS for the third quarter are anticipated to be approximately 49.6 million.
For 2015, the company expects its capital expenditures to be 5% to 9% of revenue, excluding the Chengdu site expansion.
