Operations
Input and Output Impedance
The YS12S16 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
(minimum 47 μF) 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 30 μF (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 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 YS12S16 has been designed for stable
operation with or without external capacitance. Low
ESR ceramic capacitors placed as close as possible
to the load (minimum 47 μF) 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. The typical connections are
shown in Fig. A.
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.

YS12S16 DC-DC Converter Data Sheet
The negative logic version turns the converter on
when the ON/OFF pin is at logic low or left open, and
turns the converter off when the ON/OFF pin is at a
logic high or connected to Vin.
The 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
the ON/OFF pin. When using open collector (open
drain) transistor with a negative logic option, add a
pull-up resistor (R*) of 75K 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
 0.8 V
- sourcing up to 0.25 mA at a high logic level of
2.3 V – 5 V
- sourcing up to 0.75 mA when connected to Vin.
Remote Sense (Pin 2)
The
compensates for voltage drops occurring only
between Vout pin (Pin 4) of the converter and the
load. The SENSE (Pin 2) 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.
If remote sensing is not required, the SENSE pin
must be connected to the Vout pin (Pin 4) 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.
