Korea-based specialty foundry Dongbu HiTek has announced the manufacture of products for two new China-based clients.

Dongbu HiTek announced it has begun volume producing DC/DC converters for Wuxi Silicon Technology (WST), a fabless semiconductor company based in Wuxi, China. WST's step-down converters leverage Dongbu HiTek's specialized BCDMOS 0.35-micron process to operate efficiently over wide range of input voltages (4.75V- 24V) and load currents (2A /3A).

Dongbu HiTek also disclosed in a separate company release that it is manufacturing power management ICs for Leaderchip Technology, a fabless venture based in Xi'an, China, using the foundry's low-voltage BCDMOS process (BD180LV) at the 0.18-micron node. Leaderchip's new PWM ICs will be targeted at mobile internet device (MID) and GPS applications.

In addition, Dongbu HiTek noted that the company has stepped up its support for customers in China. Earlier in 2011, it has set up customer service/sales operations in Shanghai and Shenzhen. Dongbu HiTek aims to expand its foundry business in the region.
