UNR-3.3/10-D5T-C Datasheet - ETC

[Murata-Ps]

As supply voltages trend lower and load currents increase, centralized power becomes more impractical. The tight accuracy, low noise and quick transient response demanded by todays low voltage CPUs, ASICs and DSPs make power processing at the point of use the only viable solution. The UNR 18-33W series provides a complete line of non-isolated DC/DC converters to satisfy this requirement. With input voltages of 5V (-D5 models) and 12V (-D12 models) these converters offer standard output voltages of 1.8, 2.5 and 3.3 Volts and up to 10 Amps of output current in both through-hole and surface-mount 1" x 2" metal cases.
