Description

The DCR010505U is one member of the DCR01 series.DCR01 family is a series of high-efficiency, input-isolated, output-regulated DC/DC converters. In addition to 1W nominal, galvanically-isolated output power capability, this range of DC/DCs offer very low output noise, thermal protection and high accuracy.

Features of the DCR010505U are:(1)UL1950 recognized;(2)PDIP-18, SO-28(1);(3)53W/in3 (3.3W/cm3) power density;(4)device-to-device synchronization;(5)thermal protection;(6)1000Vrms isolation;(7)400kHz switching; (8)125 fits at 55;(9)±10% input range;(10)short-circuit protected;(11)5V, 12V, 24V inputs;(12)3.3V, 5V outputs;(13)high efficiency.The DCR01 family is implemented in standard molded IC packaging, giving standard JEDEC outlines suitable for high-volume assembly.The DCR01 is manufactured using the same technology as standard IC packages, thereby achieving very high reliability.The DCR01 is a switching power supply and as such can place high peak current demands on the input supply. In order to avoid the supply falling momentarily during the fast switching pulses, ground and power planes should be used to track the power to the input of DCR01, this will also serve to reduce noise on the circuit. If this is not possible, the supplies must be connected in a star formation, with the tracks made as wide as possible.

The absolute maximum ratings of the DCR010505U can be summarized as:(1)input voltage:7V;(2)storage temperature:-60 to +125;(3)operating temperature:270.The DCR010505U can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.The DCR01 uses an internal saw-tooth generator to provide the 800kHz on-board oscillator that is used to drive the power switching circuit. The operation of the oscillator is monitored by the watchdog, which will tri-state the output driver circuit if the oscillator fails, or if the SYNC pin is taken low, (shutdown mode). When the SYNC pin is returned high, normal operation resumes.
