DCP0124 Series
Miniature 24V Input, 1W Isolated UNREGULATED DC/DC CONVERTERS
FEATURES
q STANDARD JEDEC PLASTIC PACKAGE q LOW PROFILE: 0.15" (3.8mm) q SYNCHRONIZABLE q OUTPUT SHORT CIRCUIT PROTECTION q THERMAL SHUTDOWN q STARTS INTO ANY CAPACITIVE LOAD q EFFICIENCY: 76% (±15V Out) q 1000Vrms ISOLATION q 400kHz SWITCHING q 93 MILLION HOURS MTTF q AVAILABLE IN TAPE AND REEL
DESCRIPTION
The DCP0124 family is a series of high efficiency, 24V input isolated DC/DC converters. In addition to 1W nominal galvanically isolated output power capab i l i t y , the range of DC/DCs are also fully synchronizable. The devices feature thermal shutdown, and overload protection is implemented via watchdog circuitry. Advanced power-on reset techniques give superior reset performance and the devices will start into any capacitive load up to full power output. The DCP01 family is implemented in standard-molded IC packaging, giving outlines suitable for high volume assembly.

ELECTROSTATIC DISCHARGE SENSITIVITY
This integrated circuit 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.
