SAN FRANCISCO—Specialty foundry Dongbu HiTek Co. Ltd. said Thursday (Nov. 10) it has commenced volume production for two new customers based in mainland China.
Dongbu (Seoul, South Korea) said it started volume production of DC/DC converters for Wuxi Silicon Technology (WST) and power management ICs for Leaderchip Technology Co. Ltd.
Dongbu stepped up its support of the burgeoning Chinese semiconductor market when it established customer service and sales operations in Shanghai and Shenzhen earlier this year. The firm said it aims to expand its analog IC foundry business in China by offering the broadest choice of power management IC processing technologies, including a high-voltage 700V process that will soon be added to its specialized portfolio.
"We are committed to expanding our support of analog and mixed-signal semiconductor development in China, and are very pleased that WST chose our specialized BCDMOS foundry to process their power converters," said Jae Song, Dongbu's senior vice president of sales and marketing, in a statement. "We look forward to expanding our partnership with WST as it diversifies its BCDMOS converter portfolio to include 1A/2A/3A versions implemented at the 0.18-micron node."
WST's step-down converters leverage Dongbu's specialized BCDMOS 0.35-micron process to operate over wide range of input voltages (4.75V- 24V) and load currents (2A /3A), Dongbu said.
Dongbu said it is building Leadership Tech's power management ICs with its low-voltage 0.18-micron BCDMOS process. The chips specify outstanding reliability characteristics while operating over a broad 7V-to-30V range, targeting mobile internet devices and GPS applications. Dongbu said. Leadership Tech is a fabless venture based in Xi’an, China.
"As we continue to expand our support of semiconductor development in China, we are pleased that companies such as Leaderchip Technology are choosing our specialized processing to implement their analog-intensive devices," Song said. According to Song, the BD180LV process raised the performance bar for advanced BCDMOS processes by specifying the industry’s lowest specific on-resistance.
According to iSuppli, the worldwide power management IC market is forecast to exceed $43 billion in 2015, posting a 7.2 percent compound annual growth rate (CAGR) over the prior five years. The power management IC market in China is expected to approach $15 billion in 2015, posting a 9.7 percent CAGR over the same five years as it commands about one-third of the worldwide total, according to the market research firm.
