The YNV05T100XY converters provide exceptional thermal
performance, even in high temperature environments with
minimal airflow. No derating is needed up to 85 C under
natural convection conditions. This is accomplished through
the use of circuitry, packaging, and processing techniques to
achieve ultra-high efficiency and excellent thermal
management along with a very sleek body profile.
The sleek body profile and the preclusion of heat sinks
minimize impedance to system airflow, thus enhancing
cooling for both upstream and downstream devices. The
use of 100% automation for assembly, coupled with
advanced power electronics and thermal design, results in a
product with extremely high reliability.

Input and Output Impedance

Input Voltage Ripple [mV] .
Input Voltage Ripple [mV] .
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.

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.

YNV05T100xy DC-DC Converter
ON/OFF pin is internally pulled-up to Vin for a positive logic version and pulled-down for a negative logic version. 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 with a negative logic option, 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
Remote Sense (Pin 3)
The remote sense feature of the converter compensates for voltage drops occurring only between Vout of the
converter and the load. The SENSE (Pin 3) pin should be connected at the load or at the point where regulation is
required (see Fig. D). There is no sense feature on the output GND return pin, where a solid ground plane is
recommended to provide a low voltage drop.
If remote sensing is not required, the SENSE pin must be connected to the Vout to ensure the converter will regulate
at the specified output voltage. If these connections are not made, the converter will deliver an output voltage that is
slightly higher than the specified value.

Fig. D: Remote sense circuit configuration.
Because the sense lead carries minimal current, large trace on the end-user board is not required. However, the
sense trace should be located close to a ground plane to minimize system noise and insure optimum performance.
When utilizing the remote sense feature, care must be taken not to exceed the maximum allowable output power
capability of the converter, equal to the product of the nominal output voltage and the allowable output current for the
given conditions.
When using remote sense, the output voltage of the converter can be increased up to 0.5 V above the sense point
voltage in order to maintain the required voltage across the load. Therefore, the designer must, decrease the
maximum current (originally obtained from the derating curves) by the same percentage to ensure the converter’s
actual output power remains at or below the maximum allowable output power.
Output Voltage Adjust / TRIM (Pin 9)
The converter’s output voltage can be adjusted up 10% or down 10% for Vout > 1.0 V, and +10%/-5% for Vout = 0.9
V relative to the rated output voltage by the addition of an externally connected resistor.
The TRIM pin should be left open if trimming is not being used. To minimize noise pickup, a 0.1 uF capacitor is
connected internally between the TRIM and Ground.
To trim up the output voltage, refer to Fig. E. A trim resistor (RT-INCR) should be connected between the TRIM pin (Pin
9) and output GND pin (Pin 5), with a value of:
For VO-NOM ≥ 1.2V,

YNV05T100xy DC-DC Converter
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 overcurrent and short circuit conditions. Upon sensing an over-current condition,
the converter will enter hiccup mode. Once the overload or short-circuit condition is removed, Vout will return to
nominal value.
Overtemperature 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 62368-1and IEC/EN 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 20 Amps must be used in series with the input line.
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
parameters, output ripple and noise, and transient response to load step-change.
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. G for optimum measuring thermocouple location.

Fig. G: Location of the thermocouple for thermal testing.
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 (0.15 m/s to
2.5 m/s), and vertical and horizontal converter mounting. The airflow during the testing is parallel to the long axis of
the converter, going from ON/OFF pin to output pins.
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 (10 A)
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. G should not exceed 120 °C in order
to operate inside the derating curves.
Efficiency
Fig. x.3 show the efficiency vs. load current plot for ambient temperature of 25 ºC, airflow rate of 200 LFM (1 m/s) and
input voltages of 4.5 V, 5.0 V, and 5.5 V.
Fig. x.4 show the efficiency vs. load current plot for ambient temperature of 25 ºC, airflow rate of 200 LFM (1 m/s) and
input voltages of 3.0 V, 3.3 V, and 3.6 V for output voltages 2.5 V.
Power Dissipation
Fig. 3.3V.4 shows the power dissipation vs. load current plot for Ta = 25 ºC, airflow rate of 200 LFM (1 m/s) with
vertical mounting and input voltages of 4.5 V, 5.0 V, and 5.5 V for 3.3 V output voltage.
Start-up
Output voltage waveforms, during the turn-on transient with application of Vin at full rated load current (resistive load)
are shown with 47 F external load capacitance at Vin = 5 V in Fig. x.5.
Ripple and Noise
The output voltage ripple waveform is measured at full rated load current. Note that all output voltage waveforms are
measured across a 1 F ceramic capacitor. The output voltage ripple and input reflected ripple current waveforms are
obtained using the test setup shown in Fig. H.
