1. Introduction
This evaluation kit has been designed to provide an easy way to characterize the product performance and its features.
It is intended to aid customers and determine the product suitability for the target application. The evaluation board
incorporates the required external components to demonstrate the complete product functionality. It also includes other
components (e.g. test points, etc…) to facilitate a successful end user experience. Not all these external components
are required if the product features are not needed. Details of the external components, schematics, and PCB layout
are provided in this documentation for reference only. Final design and qualification needs to be verified at customer’s
end system level.
2. Ordering Information
TDK-Lambda offers a wide variety of non-isolated dc-dc power modules in the i6A series. Not every product is currently
available in an evaluation kit. The table below includes description and ratings which should help in selecting the most
applicable evaluation kit.

3. Design Consideration
The purpose of this reference design is to assist the engineer to design the printed circuit board and select the
additional components from commonly available material.
The design is NOT full characterized. This remains in the responsibility of the end user.
TDK-Lambda Technical Support will be glad to assist you further.
IMPORTANT INFORMATION
Observe proper safety and laboratory procedures when testing electronic products. This list serves as general guide only
and not a substitute for common sense and best practices.
Before applying power, double check and ensure all connections to the evaluation board interface are correct (e.g. Input
source polarity connections, etc…).
Although highly efficient, these high power density modules can dissipate significant amounts of power, especially at heavy
load. Care should be taken to ensure adequate cooling is provided and the modules are operated within the thermal
specifications outlined in the product data sheets.
This evaluation kit is designed for general laboratory use. It is not intended for installation in end customer product or
equipment.
Please check the pertinent product (DC-DC Module) datasheets and specifications for complete information.

Current Amp:
Current Amp circuit block get output current information by using shunt resistor. EVKIT uses 10mohm resistor as
parallel, total 5mohm. It shown as R773 and R774. To reduce power loss at RSHUNT a smaller value can be used,
keeping in mind that smaller resistor will make signal smaller and reduce their accuracy. Voltage range from 5mohm
RSHUNT is 0V to 50mV for current from 0 to 10A.
Then gain signal by IC754. DC Gain is calculated as “R830/R784+1”. So approximately “25”, followed by
“0.5times” resistor divider R782 and R780. So total DC gain is 12.5.
Therefore, “0V to 50mV” from RSHUNT signal convert to “0V to 625mV”
Error Amp:
Error Amp compare between “CC_REF” and signal from current amp. Maximum current amp is 625mV.
CC_REF range is between 0V and 5V. Therefore, CC_REF maximum signal 5V must be down to 625mV by resistor
divider. R786 and R778 are chosen by equation below.
5V * R778 / (R786+R778) = 625mV
Pick R778:1.0k and R786:6.81k is good value for this example.
Trim Amp:
Output of trim amp IC752 connected to trim terminal in order to get constant current.
To change output voltage provide constant current against changing load resistance.
R775 and C771 decide how quick response for transient situation. Small value creates quick response but it
may have overshoot or undershoot. Large value create slow response but more stable.

Maximum trim down voltage for the i6A is limited
to how much current the inverter amp can pull out
of the trim pin. The used TI OPA237 Op-amp
typically pulls around -150µA.
If a wider trim range is required a better quality
Op-amp can be selected.

During On/Off or Vin start-up, the CC_REF should be set to zero before start-up. Otherwise, there will be overshoot of
output voltage and output current before settling to the final value. Depending on circuit values, it is also possible the
overshoot would cause the module to enter an over current protection hiccup mode. Generally, the recommend
sequence is apply input voltage, set reference as zero, then apply on/off signal to enable module, then finally increase
CC_REF to drive the output current to desired value.
