Efficiency up to 86% 1500VDC Isolation MTBF > 1,000,000 Hours 2:1 Wide Input Range Short Circuit Protection Complies with EN55022 Class A Temperature Performance -40] to +71] Industry Standard Pinout UL 94V-0 Package Material Internal SMD Construction
Minmax's MIW1200-Series power modules operate over input voltage ranges of 9-18VDC, 18-36VDC and 36-75VDC which provide precisely regulated output voltages of 3.3V, 5V, 12V, 15V, {5V, {12V and {15VDC. The -40] to +71] operating temperature range makes it ideal for data communication equipments, mobile battery driven equipments, distributed power systems, telecommunication equipments, mixed analog/digital subsystems, process/machine control equipments, computer peripheral systems and industrial robot systems. The modules have a maximum power rating of 3W and a typical full-load efficiency of 86%, continuous short circuit, 25mA output design-in time, cost and eliminate the need for external filtering. ripple, EN55022 Class A conducted noise compliance minimize

Notes :
1. Specifications typical at Ta=+25], resistive load, nominal input voltage, rated output current unless otherwise noted. 2. Transient recovery time is measured to within 1% error band for a step change in output load of 50% to 100%. 3. Ripple & Noise measurement bandwidth is 0-20 MHz. 4. These power converters require a minimum output loading to maintain specified regulation. 5. Operation under no-load conditions will not damage these modules; however, they may not meet all specifications listed. Min.
