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.
