MINIATURE, 1W, 3kV ISOLATED  
UNREGULATED DC/DC CONVERTERS  
FEATURES  
DESCRIPTION  
•
•
•
•
•
Up To 78% Efficiency  
The DCH01 series is a family of miniature, 1W, 3kV  
isolated DC/DC converters. Featured in an industry  
standard SIP-7 footprint, the DCH01 series requires  
minimal external components, reducing board space.  
The DCH01 series provides both single and dual  
split-supply outputs.  
3kVDC Isolation  
UL60950 Certified Product (pending)  
Industry Standard Footprint  
JEDEC SIP-7 Package  
The use of a highly integrated package design  
results in highly reliable products with high power  
densities. High performance and small size makes  
the DCH01 suitable for a wide range of applications  
including signal chain applications and ground loop  
elimination.

This integrated circuit can be damaged by ESD. Texas Instruments 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.  
ORDERING INFORMATION

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in  
a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2)  
Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check  
http://www.ti.com/productcontent for the latest availability information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and  
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS  
compatible) as defined above.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame  
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
