Microsemi Corp. introduces LX7167 2A, LX7169 3A and LX7165 5A DC-DC regulators for powering disc drives used in enterprise applications.

The LX7167 2A, LX7169 3A and LX7165 5A DC-DC regulators are based on a flexible architecture that is said to be unique to Microsemi and includes patent-pending control technology. The cost-effective implementation enables ultra-fast transient response times, while minimising power dissipation.

"The performance and technical advantages of our new regulators have already been validated by design wins from one of the industry's leading disc drive manufacturers," said Mark Smith, product line manager, DC-DC products for Microsemi. "As we execute on our product roadmap we plan to leverage the unique flexibility, control technology and ultra-fast response times of this product suite in targeting a number of applications within the growing DC-DC converter market."

According to Darnell Group in its 2011 Worldwide DC-DC Converter IC Forecast, the worldwide DC-DC converter IC market will grow from nearly 2,000 crore units in 2011 to just under 3,200 crore units in 2016.

Microsemi's DC-DC regulators are targeted at 3.3V and 5V applications and are offered in multiple output current ratings. Customers can choose from a variety of space-saving package technologies including dual flat no-lead (DFN) and wafer-level chip-scale packaging (WL-CSP).

Microsemi's patent-pending control technology claims to eliminate the need for a traditional control loop error amplifier and allows immediate response to load and line disturbances. In addition, delays associated with the control network are eliminated, enabling increased speed and lower device bias currents. The resulting speed improvement also facilitates the removal of output capacitors, which lowers component counts and bill-of-material costs.

Microsemi's regulators offer the speed needed to deliver the transient power larger capacitors would have provided in the past. The increased speed reduces output voltage excursions during transient loads as much as 3x compared to competitive solutions. In addition, the lower bias currents ensure the regulators maximise efficiencies at the lowest load currents.

The LX7167 2A and the LX7169 3A regulators are sampling now. The LX7165 5A regulator will be available in the Q1 12. All three devices will be available in production quantities in the Q1 12.
