Description
The YNL12S100xy non-isolated DC-DC converters deliver up to 10 A of output current in an industry-
standard surface-mount package. The YNL12S100xy converters operate from a 9.6 – 14 VDC input. These
converters are ideal choices for Intermediate Bus Architectures where point-of-load power delivery is
generally a requirement.
Within the YNL12S100xy family, converters come in individual output voltage versions, allowing coverage of
the output voltage range from 1.0 to 5.0 V. Each version is capable of providing an extremely tight, highly
regulated, and trimmable output.
The YNL12S100xy converters provide exceptional thermal performance, even in high temperature
environments with minimal airflow. No derating is required up to 85
o
C (up to 70
o
C for 5 V output). This is
accomplished through the use of circuitry, packaging, and processing techniques to achieve ultra-high
efficiency, excellent thermal management, and a very low body profile.
The low 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
The YNL12S100xy 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 in order to ensure converter stability
and reduce input ripple voltage. The converter has
an internal input capacitance of 20
μF
with very
low ESR (ceramic capacitors).
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 47
μF-100 μF
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 YNL12S10 has been designed for stable
operation with no external capacitance as well with
external capacitance. Low ESR ceramic
capacitors placed as close as possible to the load
(minimim of 47μF) are recommended for improved
transient performance and lower output voltage
ripple.
It is important to keep low resistance and low
inductance PCB traces for connecting load to the
output pins of the converter in order to maintain
good load regulation.
ON/OFF (Pin 1)
The ON/OFF pin is used to turn the power
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. A.

TRIM
R* is for negative logic option only
Fig. A:
Circuit configuration for ON/OFF function.
The positive logic version turns the converter on
when the ON/OFF pin is at a logic high or left
open, and turns the converter off when at a logic
low or shorted to GND.
The negative logic version turns the converter on
when the ON/OFF pin is at a logic low or left open,
and turns converter off when the ON/OFF pin is at
a logic high or connected to Vin.
ON/OFF pin is internally pulled-up to Vin for
positive logic version, and pulled-down for
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 75 k to Vin as shown
in Fig. A; This device must be capable of:
- sinking up to 0.2 mA at a low level voltage of
0.8V
- sourcing up to 0.25 mA at a high logic level of
2.3V – 5V
- sourcing up to 0.75 mA when connected to Vin.
Remote Sense (Pin 2)
The remote sense feature of the converter
compensates for voltage drops occurring only
between Vout pin of the converter and the load.
The SENSE pin should be connected at the load
or at the point where regulation is required (see
Fig. B). There is no sense feature on the output
GND return pin, where the solid ground plane
should provide low voltage drop.
