YS05S10 DC-DC Converter Data Sheet
3.0-5.5 VDC Input; 0.7525-3.63 VDC Programmable @ 10 A
Operations
Input and Output Impedance
The YS05S10 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.
The use of decoupling capacitors is recommended in
order to ensure stability of the converter and reduce
input ripple voltage. Internally, the converter has
44 μ F (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
100 - 200 μ F 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 YS05S10 has been designed for stable
operation with or without external capacitance. Low
ESR ceramic capacitors placed as close as possible
to the load (minimum 100 μ F) 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, with ON/OFF
signal referenced to GND. The typical connections
are shown in Fig. A.
To turn the converter on the ON/OFF pin should be
at a logic low or left open, and to turn the converter
off the ON/OFF pin should be at a logic high or
connected to Vin. See the Electrical Specifications
for logic high/low definitions.
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 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
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. This device must be capable of:
– sinking up to 1.2 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 - 5.5 V.
When using open-collector (open-drain) transistor
with a negative logic option, add a pull-up resistor
(R*) to Vin as shown in Fig. A:
– 20 K, if the minimum Vin is 4.5 V
– 10 K, if the minimum Vin is 3.0 V
– 5 K, if the undervoltage shutdown at 2.05 - 2.15 V
is required.
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
