DC/DC Converters TON 15WI Series, 15 Watt CB Features UL 60950-1 Scheme Ultra compact 15W converter Ultra wide 4:1 input voltage range Cost efcfi ient 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 40C to +85C Remote On/Off Lead free design, RoHS compliant 3-years product warranty The TON-15WI series is a generation of high performance 15W dc-dc converters with ultra-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 efcfi ient alternative to existing 10 to 15W converters in the market. Built-in lfi ters for both input and output minimize the need for external ltfi ering. Further features include remote On/Off, output voltage trimming, over voltage protection and short circuit protection. Typical applications are distributed power systems, instrumentation and industrial electronics, everywhere where space on the PCB is a critical factor.
