Input and Output Impedance

Input Voltage Ripple [mV] .
Input Voltage Ripple [mV] .
The YNV05T06 converter 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 20μF of Low ESR Ceramic Capacitance on board.
In a typical application, low ESR tantalum or POS capacitors (with sufficient ripple current rating) would be sufficient to
provide adequate ripple voltage attenuation 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.
YNV05T06 has been designed for stable operation with or without external 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 connecting the load to the output pins of
the converter. This is required to maintain good load regulation since the converter does not have a SENSE pin for
compensating voltage drops associated with the power distribution system on your PCB.

shown in Fig. B with one 470μF polymer capacitor (6TPB470M from Sanyo) in parallel with two 47μF ceramic capacitors
at 5A load.
ON/OFF (Pin 5)
The ON/OFF pin (Pin 5) is used to turn the power converter on or off remotely via a system signal that is referenced to
GND (Pin 3). Typical connections are shown in Fig. C.
To turn the converter on the ON/OFF pin should be at a logic low or left open, and to turn the converter off the ON/OFF
pin should be at a logic high or connected to Vin
ON/OFF pin is internally pulled-down. A TTL or CMOS logic gate, open collector (open drain) transistor can be used to
drive ON/OFF pin. When using open collector (open drain) transistor, add a pull-up resistor (R*) of 10K to Vin as shown
in Fig. C. External pull-up resistor (R*) can be increased to 20K if minimum input voltage is more than 4.5V. This device
must be capable of:
–
–
sinking up to 0.6 mA at a low level voltage of 0.8 V
sourcing up to 0.25 mA at a high logic level of 2.3V – 5.5V

Output Voltage Programming (Pin 2)
The output voltage can be programmed from 0.7525V to 3.63V by connecting an external resistor between TRIM pin (Pin
2) and GND pin (Pin 3); see Fig. D. Note that when a trim resistor is not connected, the output voltage of the converter is
0.7525V.
A trim resistor, RTRIM, for a desired output voltage can be calculated using the following equation:
RTRIM =
21.07
− 5.11
(VO -REQ - 0.7525)
[k]
where,
RTRIM = Required value of trim resistor [k]
VO−REQ = Desired (trimmed) output voltage [V]
Note that the tolerance of a trim resistor directly affects the output voltage tolerance. It is recommended to use standard
1% or 0.5% resistors; for tighter tolerance, two resistors in parallel are recommended rather than one standard value
from Table 1.
The ground pin of the trim resistor should be connected directly to the converter GND pin with no voltage drop in between.
Table 1 provides the trim resistor values for popular output voltages.

The output voltage can also be programmed by an external voltage source. To make trimming less sensitive, a series
external resistor Rext is recommended between the TRIM pin and the programming voltage source. Control Voltage can

Input Undervoltage Lockout
Input undervoltage lockout is standard with this converter. The converter will shut down when the input voltage drops
below a pre-determined voltage; it will start automatically when Vin returns to a specified range.
The input voltage must be typically 2.05V for the converter to turn on. Once the converter has been turned on, it will shut
off when the input voltage drops below typically 1.9V.
Output Overcurrent Protection (OCP)
The converter is protected against over-current and short circuit conditions. Upon sensing an over-current condition, the
converter will enter hiccup mode. Once an overload or short-circuit condition is removed, Vout will return to nominal
value.
Over-Temperature Protection (OTP)
The converter will shut down under an over-temperature condition to protect itself from overheating caused by operation
outside the thermal derating curves, or operation in abnormal conditions such as system fan failure. After the converter
has cooled to a safe operating temperature, it will automatically restart.
Safety Requirements
Approved to the latest edition and amendment of ITE Safety standards, UL/CSA 62368-1 and EN/IEC 62368-1
The maximum DC voltage between any two pins is Vin under all operating conditions. Therefore, the unit has ELV (extra
low voltage) output; it meets ES1 requirements under the condition that all input voltages are ELV.
The converter is not internally fused. To comply with safety agencies requirements, a recognized fuse with a maximum
rating of 15 Amps must be used in series with the input line.

YNV05T06 DC-DC Converter
General Information
The converter has been characterized for many operational aspects, to include thermal derating (maximum load current
as a function of ambient temperature and airflow) for vertical and horizontal mounting, efficiency, start-up and shutdown
parameters, output ripple and noise, transient response to load step-change, overload and short circuit.
The figures are numbered as Fig. x.y, where x indicates the different output voltages, and y associates with specific plots
(y = 1 for the vertical thermal derating …). For example, Fig. x.1 will refer to the vertical thermal derating for all the output
voltages in general.
The following pages contain specific plots or waveforms associated with the converter. Additional comments for specific
data are provided below.
Test Conditions
All thermal and efficiency data presented were taken with the converter soldered to a test board. Specifically, a 0.060”
thick printed wiring board (PWB) with four layers. The top and bottom layers were not metalized. The two inner layers,
comprising two-ounce copper, were used to provide traces for connectivity to the converter.
The lack of metalization on the outer layers as well as the limited thermal connection ensured that heat transfer from the
converter to the PWB was minimized. This provides a worst-case but consistent scenario for thermal derating purposes.
All measurements requiring airflow were made in vertical and horizontal wind tunnel facilities using Infrared (IR)
thermography and thermocouples for thermometry.
Ensuring components on the converter do not exceed their ratings is important to maintaining high reliability. If one
anticipates operating the converter at or close to the maximum loads specified in the derating curves, it is prudent to
check actual operating temperatures in the application. Thermographic imaging is preferable; if this capability is not
available, then thermocouples may be used. Bel Power Solutions recommends the use of AWG #40 gauge
thermocouples to ensure measurement accuracy. Careful routing of the thermocouple leads will further minimize
measurement error. Refer to Fig. E for optimum measuring thermocouple location.
Thermal Derating
Load current vs. ambient temperature and airflow rates are given in Figs. x.1 to x.2 for maximum temperature of 120°C.
Ambient temperature was varied between 25°C and 85°C, with airflow rates from 30 to 500 LFM (0.15m/s to 2.5 m/s), for
Vin = 5V and Vin = 3.3V, and vertical or horizontal converter mounting.
For each set of conditions, the maximum load current was defined as the lowest of:
(i) The output current at which any MOSFET temperature does not exceed a maximum specified temperature (120°C) as
indicated by the thermographic image, or
(ii) The maximum current rating of the converter (6A)
During normal operation, derating curves with maximum FET temperature less than or equal to 120°C should not be
exceeded. Temperature on the PCB at the thermocouple locations shown in Fig. E should not exceed 120°C in order to
operate inside the derating curves.
Fig. E: Location of the thermocouple for thermal testing.
Efficiency
Fig. x.3 show the efficiency vs. load current plot for ambient temperature of 25ºC, airflow rate of 200 LFM (1 m/s) with
vertically or horizontally mounting and input voltages of 4.5V, 5.0V and 5.5V.
Fig. x.4 show the efficiency vs. load current plot for ambient temperature of 25ºC, airflow rate of 200 LFM (1 m/s) with
vertically or horizontally mounting and input voltages of 3.0V, 3.3V, and 3.6V for output voltages 2.5V.
