Glary Power Intros COQ48S018-40 DC/DC Converter

Glary Power Technology (Taichung, Taiwan) introduced the COQ48S018-40 0.34in high, quarter-brick, dc/dc converter, which delivers rated current across the input-voltage range from 36V to 75V, a –40 to +110 degrees C base temperature range, 1.8V/40A of high efficiency, a 35A/in³ current density, and a full-load conversion efficiency of 88 percent.

The patented "buck-reset" topology with an SR stage reduces the total power loss, resulting in more delivered current and a higher conversion efficiency. The single-component side structure provides a low thermal resistance, heat-conduction path to remove the heat from power components to the base plate directly.

The converter features a 1.5kVdc isolation rating between primary to secondary and is designed to meet international safety standards, including EN60950 and CSA/UL60950. The converter also provides full protection functions such as over-voltage, over-temperature and input under-voltage lockout. The module offers an output-voltage trim facility that enables the output to be adjusted between 90 and 110 percent of nominal. The option of remote-control logic is available for different control signals.

The COQ48S018-40 dc/dc converters are now available. Pricing is $76.5 each in 1,000-unit quantities.
