Taking up as little as 0.16 square inches of board space, Minmax's MFU100 1W DC/DC's are specially designed to provide power distribution
applications where space is critical in an ultra-miniature DIP package. The series consists of 12 models with input voltages of 5V, 12V and 24VDC which offers standard single output voltages of 5V, 9V, 12V, 15VDC. The MFU100 series is an excellent selection for a variety of applications including distributed power systems, mixed analog/digital subsystems,
portable test equipments, local power networks and battery backed systems.

Notes :
1. Specifications typical at Ta=+25¢XC, resistive load, nominal input voltage, rated output current unless otherwise noted.
2. Ripple & Noise measurenent bandwidth is 0-20 MHz.
3. These power converters require a minimum output load to maintain specified regulation.
4. Operation under no-load conditions will not damage these modules; however, they may not meet all specifications listed.
5. All DC/DC converters should be externally fused at the front end for protection.
6. Other input and output voltage may be available, please contact factory.
7. specifications subject to change without notice.
