DC-DC Converter Modules: HNDS/HNAS Series

Shindengen Electric Manufacturing Co., Ltd. (headquartered in Otemachi, Chiyoda-ku, Tokyo, Japan)
imagined“a design to save energy easily just by putting it on top”when we developed the two types of non-insulating step-down DC-DC converter modules called the HNDS series and HNAS series.March 2009 marks the start of mass production, with over 1 million shipments expected in the first year, mainly to the industrial device market.

Designed to save energy easily just by putting on top!
HNDS series supports 12 V/24 V-type input
HNAS series supports 3.3 V/5 V-type input
Supports high-current (3 A) output
Incorporates comprehensive protection functions
Full range of mounting variations

1．Overview

　In recent years, as momentum for protection of the global environment rises, energy-saving demands have intensified for devices of all kinds, not just products for consumers. Likewise, the market for industrial devices requires cuts in power consumption.
　To improve response speed and lower power consumption in memory and system LSIs used in industrial device control, etc., leaps are being made in lowering voltage and raising current. Power specifications, accordingly, grow increasingly diverse and complex. However, as faster product development is demanded of power design, it is becoming impossible to devote adequate time to consideration. Therefore, a number of cases can be seen in which the dropper method is used despite its low conversion efficiency because it is easy to design with, one factor slowing the movement towards energy conservation.
　We, however, have developed the concept of “a design to save energy easily just by putting it on top”into the non-insulating step-down DC-DC converter module HNDS series and HNAS series. It eliminates design headaches while helping to save energy with high-efficiency power. We have 3 mounting variations, considerate of the details of power designers' needs.

　We shall continue to provide high-efficiency power responsive to power designers' needs and to contribute to the protection of the global environment.
