DCH01 Series
SBVS073C MAY 2006 REVISED AUGUST 2006
MINIATURE, 1W, 3kV ISOLATED
UNREGULATED DC/DC CONVERTERS
Up To 78% Efficiency
The DCH01 series is a family of miniature, 1W, 3kV
isolated DC/DC converters. Featured in an industry
3kVDC Isolation
standard SIP-7 footprint, the DCH01 series requires
UL60950 Certified Product (pending)
minimal external components, reducing board space.
Industry Standard Footprint
The DCH01 series provides both single and dual
JEDEC SIP-7 Package
split-supply outputs.
The use of a highly integrated package design
results in highly reliable products with high power
Point-of-Use Power Conversion
densities. High performance and small size makes
the DCH01 suitable for a wide range of applications
Ground Loop Elimination
including signal chain applications and ground loop
Data Acquisition

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.
For the most current package and ordering information, see the Package Option Addendum at the end of this
data sheet, or see the TI website at www.ti.com.

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.

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)
