Description  
Power-One’s point-of-load converters are recommended for use with regulated bus converters in an Intermediate  
Bus Architecture (IBA). The YV09T60 non-isolated DC-DC point of load (POL) converter delivers up to 60A of  
output current in an industry-standard single-in-line (SIP) through-hole package. The YV09T60 POL converter is  
an ideal choice for Intermediate Bus Architectures where point of load conversion is a requirement. Operating  
from a 5-13.8V input the POL converter provides an extremely tightly regulated programmable output voltage of  
0.6 V to 3.63V. The POL converters offer exceptional thermal performance, even in high temperature  
environments with minimal airflow. This performance is accomplished through the use of advanced circuit  
solutions, packaging and processing techniques. The resulting design possesses ultra-high efficiency, excellent  
thermal management, and a slim body profile that minimizes impedance to system airflow, thus enhancing cooling  
for both upstream and downstream devices. The use of automation for assembly, coupled with advanced power  
electronics and thermal design, results in a product with extremely high reliability.

The solder exemption refers to all the restricted materials except lead in solder. These materials are Cadmium (Cd), Hexavalent chromium  
(Cr6+), Mercury (Hg), Polybrominated biphenyls (PBB), Polybrominated diphenylethers (PBDE), and Lead (Pb) used anywhere except in  
solder.  
Example: YV09T60-0G: YV09T60 POL converter with positive ON/OFF logic, 0.6 to 1.98V output voltage range,  
and lead-free solder. Refer to Figure 1 for label marking information.

6. Application Information  
6.1 Input and Output Impedance  
The POL converter should be connected to the DC  
power source via low impedance.  
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.  
Internally, the converter includes 110μF (low ESR  
ceramics) of input capacitance which eliminates the  
need for external input capacitance. However, if the  
distribution of the input voltage to the POL converter  
contains high inductance, it is recommended to add  
a 150μF decoupling capacitor placed as close as  
possible to the converter input pins. A low-ESR  
tantalum or POS capacitor connected across the  
input pins help ensuring stability of the POL  
converter and reduce input ripple voltage.

A 470μF POS, tantalum, or ceramic output capacitor  
is recommended to improve output ripple and  
dynamic response.  
It is important to keep low resistance and low  
inductance of PCB traces for connecting load to the  
output pins of the converter in order to maintain good  
load regulation.

recommended to control the ON/OFF pin with an  
open collector transistor or similar device.  
6.4 Remote Sense (Pins 10 and 11)  
If the RTRIM is not used and the Sense+ and Sense-  
pins are shorted to Vout and GND respectively, the  
output voltage of the POL converter will be 0.6V. No  
capacitor is allowed between Trim+ and Trim- pins.  
The remote sense feature compensates for the  
voltage drop between the output pins of the POL  
converter and the load. The Sense- (Pin 10) and  
Sense+ (Pin 11) pins should be connected at the  
load or at the point where regulation is required  
(refer to Figure 28).  
Note that the trim resistor tolerance directly affects  
the output voltage accuracy. It is recommended to  
use ±0.1% trim resistors to meet the output voltage  
setpoint accuracy specified in p. 4.2.  
If remote sensing is not required, the Sense pins  
must be connected to the Vout and GND pins  
directly at the output of the POL converter.

Because the sense leads carry minimal current,  
large traces on the end-user board are not required.  
The voltage sense traces should be located close to  
a ground plane to minimize system noise.

6.3 ON/OFF (Pin 9)  
The ON/OFF pin is used to turn the POL converter  
ON or OFF remotely by a signal from a system  
controller. For positive logic, the POL converter is  
ON when the ON/OFF pin is at a logic high (2.4V  
min) or left open. The POL converter is OFF when  
the ON/OFF pin is at a logic low (1.2V max) or  
connected to GND.  
When using remote sense, the output voltage at the  
converter can be increased by up to 0.5V in order to  
maintain the required voltage at the load. However,  
the maximum output voltage measured directly  
between the Vout and GND pins shall not exceed  
3.63V. In addition it is the user’s responsibility to  
ensure the POL converter’s actual output power  
always remains at or below the maximum allowable  
output power obtained from the derating curves.  
The typical connections are shown in Figure 27.

8. Safety  
The YV09T60 POL converters do not provide  
isolation from input to output. The input devices  
powering YV09T60 must provide relevant isolation  
requirements according to all IEC60950 based  
standards. Nevertheless, if the system using the  
converter needs to receive safety agency approval,  
certain rules must be followed in the design of the  
system. In particular, all of the creepage and  
clearance requirements of the end-use safety  
6.5.3  
The POL converter is protected against overcurrent  
and short circuit conditions. Upon sensing an  
Output Overcurrent Protection  
overcurrent condition, the POL converter will enter  
hiccup mode of operation. Once the overload or  
short circuit condition is removed, the POL converter  
will automatically restart and Vout will return to its  
nominal value.  
requirements must be observed.  
These  
requirements are included in UL60950 - CSA60950-  
00 and EN60950, although specific applications may  
have other or additional requirements.  
6.5.4  
Output Overvoltage Protection  
The POL converter is protected against overvoltage  
on the output. If the output voltage is higher than  
125% of its nominal value set by the RTRIM, the high  
side MOSFETS will be immediately turned off and  
the low side MOSFETs will be turned on. The POL  
converter will remain in the state until the output  
voltage reduces below 115% of its nominal value. At  
that point the POL converter will automatically  
restart.  
The YV09T60 POL converters have no internal fuse.  
If required, the external fuse needs to be provided to  
protect the converter from catastrophic failure. Refer  
to the “Input Fuse Selection for DC/DC converters”  
application note on www.power-one.com for proper  
selection of the input fuse. Both input traces and the  
chassis ground trace (if applicable) must be capable  
of conducting a current of 1.5 times the value of the  
fuse without opening.  
7. Characterization  
7.1 Ripple and Noise  
To comply with safety agencies’ requirements, a  
recognized fuse must be used in series with the input  
line. The fuse must not be placed in the grounded  
input line. Abnormal and component failure tests  
were conducted with the POL input protected by a  
fast-acting 45A, 32V fuse. If a fuse rated greater  
than 45A is used, additional testing may be required.  
The output voltage ripple and input reflected ripple  
current waveforms are measured using the test  
setup shown in Figure 29.

The maximum DC voltage between any two pins is  
Vin under all operating conditions. In order for the  
output of the YV09T60 POL converter to be  
considered as SELV (Safety Extra Low Voltage),  
according to all IEC60950 based standards, the input  
to the POL needs to be supplied by an isolated  
secondary source providing a SELV also.
