Minmax's MIW2300-Series power modules operate over input voltage ranges of 9-36VDC and 18-75VDC which provide precisely
regulated output voltages of 3.3V, 5V, 12V, 15V, {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 84%, continuous short circuit, 40mA output ripple,
EN55022 Class A conducted noise compliance minimize design-in time, cost and eliminate the need for external filtering.

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 75% 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.
6. All DC/DC converters should be externally fused at the front end for protection.
7. Other input and output voltage may be available, please contact factory.
8. Specifications subject to change without notice.
