DC/DC Converters TON 15 Series, 15 Watt RoHS compliant Features ◆ Smallest 15W Converter pending Ultra compact Size: 27.9 x 23.9 x 8.5mm ◆ Cost efficient open Frame Design with Industry Standard Pin-out ◆ Surface-mount (SM) and Through-hole Version ◆ I/O Isolation Voltage 2250V, rated for basic Insulation ◆ Extended Operating Temperature Range: –40°C to +85°C ◆ ◆ ◆ ◆ ◆ Input Filter meets EN55022, Class A Under Voltage Lockout Remote On/Off Lead free Design, RoHS compliant 3 Years Product Warranty The TON-15 series is a new generation of high performance 15W dc-dc converters with wide input voltage range and precisely regulated output voltage. The ultra compact open frame design with industry standard pin-out provides the designer now a 50% smaller, cost efficient alternative to existing 10 to 15W converters in the market. Built-in filters for both input and output minimize the need for external filtering. Further features include remote On/Off, output voltage trimming, over voltage protection, under voltage lockout and short circuit protection. Typical applications are distributed power systems, instrumentation and industrial electronics, everywhere where space on the PCB is a critical factor.
