Dongbu HiTek unveils low-voltage BCDMOS process for efficient power management

Dongbu HiTek today announced the immediate availability of a Low Voltage BCDMOS Process (BD130LV) at the 0.13-micron node that is ideally suited for implementing the main Power Management IC (PMIC) for smart phones and tablet computers.

“By moving from 0.18-micron to 0.13-micron BCDMOS processing, our new low-voltage process substantially reduces the amount of silicon area needed to implement the most desirable PMIC functions,” said Jae Song, Dongbu HiTek EVP of marketing. “Indeed, our BD130LV process includes high-speed switching DC-DC converters, high-efficiency low-dropout regulators (LDOs), a low-noise class D audio CODEC and LED backlighting as well as battery charger circuitry that provides up to 2.0 amps output.”

Song emphasized that his firm’s specialized BCDMOS enables the industry’s lowest on-resistance (Rdson). Minimizing leakage current and power consumption, the process also supports popular operating voltages from 1.5V to 6V as well as 1.2V to comply with USB battery charging specifications. “We believe our BD130LV offers fabless firms an unsurpassed range of options in designing high-efficiency PMICs for compact mobile products,” he added.

The foundry compatible BD130LV process deploys industry-leading N/PLDMOS transistors that operate up to 40V. Fully isolated nLDMOS transistors that operate up to 20V are also available along with MIM capacitance values adjusted to operating voltage, high-sheet poly resistors at various values, Schottky Diode and Bipolar transistors plus devices that protect against ESD. Royalty free memory may also be accessed. As with all Dongbu HiTek processes, the new BD130LV is supported by a fully characterized process design kit (PDK) and standard CAD tools.

The PMIC market for smart phone and tablet computers, according to iSuppli, is forecast to grow from approximately $3.0 billion this year to more than $3.5 billion in 2017, representing a CAGR of more than five percent. Dongbu HiTek’s specialized Analog and BCDMOS processes are well suited to implement chips for this segment as well as others in the overall PMIC market, which are expected to experience steady growth through 2017.
