Sharp Develops and Will Introduce New Coil-Integrated DC-DC Converter Module*1

Industry’s Most Compact Package Size*2

Press Release

Sharp Corporation has developed the new PQ5CM03 DC-DC converter module with integrated coil that features the industry’s most compact package size (9.0 x 6.0 x 2.6 [H] mm).

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 (direct current) voltages.

This module features a newly developed IC that provides a higher switching frequency*3 (1 MHz)*4, and by miniaturizing the coil, achieves the industry’s smallest size. It supports low-voltage step-down conversion from 12 V DC input to 1.2 V 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.

Product name Coil-integrated DC-DC converter module
Model name PQ5CM03
Sample price (tax included) 400 yen
Sample availability date June 30, 2010
Mass production date September 30, 2010
Monthly production capacity 550,000 units

Major Features

1. Higher switching frequency makes it possible to achieve the industry’s smallest package size (9.0 x 6.0 x 2.6 [H] mm).
2. Compact size combined with low-voltage step-down conversion from 12 V DC input voltage to 1.2 V DC output voltage.
*1 Module that converts from one DC voltage level to another.
*2 As of June 16, 2010, for 3-ampere class with integrated coil; based on Sharp research.
*3 Frequency at which the input voltage is switched on and off.
*4 Switching frequency of Sharp’s existing DC-DC converter that requires an external coil (PQ1CX53H2MPQ) is 400 kHz.
