DCNSR Series

The DCNSR series consists of high performance non-isolated DC/DC converters that can deliver 1A of output current in a small 0.46” x 0.40” x 0.30” 3-Pin SIP package. This series features a wide operating temperature range of -40°C to +85°C, efficiency up to 95.5%, and low ripple and noise. These converters are also protected against over current, over temperature, and short circuit conditions. These converters are suited to replace 78xx linear regulators and can be used to convert a positive voltage into a negative voltage. The DCNSR series is RoHS compliant and has UL60950-1, EN60950-1, and IEC60950-1 safety approvals. These converters are suitable for use in wireless networks, telecom/datacom, industry control systems, semiconductor equipment, distributed power architectures, and microprocessor power applications. The DCNSR series also has two pin types available.
