DESCRIPTION

DCR01 family is a series of high-efficiency, input-

isolated, output-regulated DC/DC converters. In addi-

tion to 1W nominal, galvanically-isolated output power

capability, this range of DC/DCs offer very low out-

put noise, thermal protection and high accuracy.

The DCR01 family is implemented in standard molded

IC packaging, giving standard JEDEC outlines suit-

able for high-volume assembly.

The DCR01 is manufactured using the same technol-

ogy as standard IC packages, thereby achieving very

high reliability.

NOTE: (1) SO version available Q3 2000.
