Introduction
The Analog Control 3623 and 4623 ChiP DCM evaluation boards described in this document are
designed to be used with the DCM family of isolated, DC-DC converters. The 3623 DCM board is used
for the analog control, low input voltage 3623 ChiP products, while the 4623 DCM board is used for
the analog control, high input voltage (offline) 4623 ChiP products.
The DCM evaluation board can be configured for various enabling and fault monitoring schemes,
as well as to exercise various modes of trimming, depending on the application requirements. The
evaluation board can be used to evaluate DCMs in either a stand-alone configuration, or as an
array of modules.

Enable options:
1.
2.
On-board mechanical switch (default)
External control
Trim options:
1.
2.
3.
Fixed trim operation (default): the TR pin is permitted to float at initial startup.
The DCM disables output trimming and the output trim is programmed to the nominal rated V
OUT
.
Variable trim operation, on-board variable resistor: The trim pin voltage is ratiometric,
with a rheostat working against a pull-up resistor inside the DCM to VCC.
Variable trim operation, off-board control: The trim pin voltage is controlled via external
programming control, which is referenced to the –IN of each specific DCM in the system.
Fault monitor options:
1.
2.
On-board LED: the FT pin drives a visible LED for visual feedback on fault status.
On-board optocoupler: the FT pin drives an on-board optocoupler to bring
fault status across the primary-secondary isolation boundary.
