Minmax's MIHW1000-Series power modules are specially designed to provide ultra-high levels of isolation 5600VDC in a low profile 24-pin DIP
package. Operating input voltage ranges of 4.5-9VDC, 9-18VDC, 18-36VDC and 36-75VDC which provide precisely regulated output voltages of
5V, 12V, 24V ,{12V and {15VDC.
The -40] to +75] 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, EN55022 Class B 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.
