Output Voltage Adjustment: The output voltage of
the power module may be adjusted by using an
external resistor connected between the Vout trim
terminal and GND terminal. If the output voltage
adjustment feature is not used, trim terminal should be
left open. Care should be taken to avoid injecting
noise into the power module’s trim pin. A small
0.01uF capacitor between the power module’s trim pin
and GND pin may help avoid this.left open.

Circuit to increase output voltage
With a resistor between the trim and GND terminals,
the output voltage is adjusted up. To adjust the output
voltage from Vo,nom to Vo,up the trim resistor should
be chosen according to the following equation:
Ru := ^{}_{(Vou(pV−}^{refV⋅Fo)nom) ohm}
The values of Vref and F are found in the electrical
data section for the power module of interest. The
maximum power available from the power module is
fixed. As the output voltage is trimmed up, the
maximum output current must be decreased to
maintain the maximum rated power of the module.
e.g. Vo = 1.8V
Ru := ^{}_(01..589^{⋅−1000.5090)}
EMC Considerations: TDK Innoveta power modules
are designed for use in a wide variety of systems and
applications. For assistance with designing for EMC
compliance, please contact TDK Innoveta technical
support.
Input Impedance:
The source impedance of the power feeding the
DC/DC converter module will interact with the DC/DC
converter. To minimize the interaction, low-esr
capacitors should be located at the input to the
module. It is recommended that a 22uF ceramic input
capacitor be placed as close as possible to the
module. Data is provided on the electrical
characteristics page, showing the typical input ripple
voltage with two 22uF ceramic capacitors (TDK part
C3225X7R1C226MT).
Reliability:
The power modules are designed using TDK
Innoveta’s stringent design guidelines for component
derating, product qualification, and design reviews.
The MTBF is calculated to be greater than 15M hours
at full output power and Ta = 40˚C using the Telcordia
SR-332 calculation method.
Quality:
TDK Innoveta’s product development process
incorporates advanced quality planning tools such as
FMEA and Cpk analysis to ensure designs are robust
and reliable. All products are assembled at ISO
certified assembly plant
