YNV05T100xy DC-DC Converter Family Data Sheet
3.0-5.5 VDC Input; 0.9-3.3 VDC Output @ 10A
Operation
Input and Output Impedance
YNV05T100XY converters should be connected
via a low impedance to the DC power source. In
many applications, the inductance associated with
the distribution from the power source to the input
of the converter can affect the stability of the
converter. It is recommended to use decoupling
capacitors (minimum 47μF) placed as close as
possible to the converter input pins in order to
ensure stability of the converter and reduce input
ripple voltage. Internally, the converter has 52uF
(low ESR ceramics) of input capacitance.
In a typical application, low - ESR tantalum or
POS capacitors will be sufficient to provide
adequate ripple voltage filtering at the input of the
converter. However, very low ESR ceramic
capacitors 47μF-100μF are recommended at the
input of the converter in order to minimize the
input ripple voltage. They should be placed as
close as possible to the input pins of the converter.
The YNV05T100xy has been designed for stable
operation
with
or
without
external
output
capacitance. Low ESR ceramic capacitors placed
as close as possible to the load (Min 47μF) are
recommended for improved transient performance
and lower output voltage ripple.
It is important to keep low resistance and low
inductance PCB traces when the connecting load
to the output pins of the converter in order to
maintain good load regulation.

Fig. B: Input Voltage Ripple, CIN = 470 μF polymer +

Fig. A shows input voltage ripple for various output
voltages using four 47μF input ceramic capacitors.
The same plot is shown in Fig. B with one 470μF
polymer capacitor (6TPB470M from Sanyo) in
parallel with two 47μF ceramic capacitors at full
load.
ON/OFF (Pin 10)
The ON/OFF pin is used to turn the converter on
or off remotely via a system signal. There are two
remote control options available, positive logic
(standard option) and negative logic, and both are
referenced to GND. Typical connections are
shown in Fig. C.

The positive logic version turns the converter on
when the ON/OFF pin is at a logic high or left
open, and turns converter off when at a logic low
or shorted to GND.
