YNC12S20 DC-DC Converter Data Sheet

9.6-14 VDC Input; 0.7525-5.5 VDC Programmable @ 20 A

Operation

Input and Output Impedance

The Y-Series 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 stability of the

converter and reduce input ripple voltage. The

converter has an internal input capacitance of 40

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 47μF-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.

YNC12S20

has

been

designed

for

stable

operation with or without external capacitance.

Low ESR ceramic capacitors placed as close as

possible to the load (Min 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. 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.

Fig. A: Circuit configuration for ON/OFF function.

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.

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 75 kΩ 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

2.3V – 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 (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 a solid ground

plane is recommended to 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.
