TMR3-4811WI

DC/DC Converters TMR 3WI Series, 3 Watt Features ◆ Highest power density in SIP package ◆ Ultra wide 4:1 input range ◆ Small footprint: 21.8 x 9.2 mm ◆ Temperature range –40° to +85°C ◆ High efficiency up to 81% ◆ Excellent load and line regulation ◆ Short-circuit protection ◆ I/O isolation 1500 VDC ◆ Remote On/Off control ◆ 3-year product warranty pending The TMR-3WI series is a new family of isolated 3W DC/DC converters with regulated output, featuring ultra-wide 4:1 input voltage range. The product comes in a ultra-compact SIP plastic package with a small footprint occupying only 2.0 cm2 (0.3 square in.) of board space. An excellent efficiency allows –40° to +85°C operation temperatures. Further features include remote On/Off control and continuous short circuit protection. The very compact dimensions of these converters make them an ideal solution for many space critical applications in battery-powered equipment and instrumentation.
