Sharp Develops Coil-Integrated DC-DC Converter Module

June 17, 2010 by Jeff Shepard

Sharp Corp. has developed the new PQ5CM03 dc-dc converter module with an integrated coil that features what the company says is the industry’s most compact package size (9.0 x 6.0 x 2.6mm).

Electronic equipment such as LCD TVs and Blu-ray Disc recorders incorporate a variety of dc-powered devices to improve performance and reduce energy consumption, and manufacturers are demanding more compact size and greater conversion efficiency of the dc-dc converters that convert between these dc voltages.

This module features a newly developed IC that provides a higher switching frequency (1 MHz), and by miniaturizing the coil, achieves what Sharp says is the industry’s smallest size. It supports low-voltage step-down conversion from 12Vdc input to 1.2V output. In addition, embedding peripheral circuit components such as the coil in the same package will contribute to a shorter development term for new electronic equipment and products.

The PQ5CM03 have an input voltage range of 8.5 to 14V, an output voltage range of 1.1 to 3.3V. The devices have an output current of 3A with a switching frequency of 1 MHz. They have a conversion efficiency of 82% and an operating temperature range of -10 to +85°C.

The coil-integrated dc-dc converter module, PQ5CM03, is sample priced (tax included) at 400 yen, with sample availability at June 30, 2010, and mass production scheduled for September 30, 2010.
