Product Name :   5pcs Input 2.5-5.5V Output 0.6-5V Adjustable DC DC Converter Buck Module Synchronous Step-Down Regulator  
   
 
Packing list:
 
5 PCS DD05AJSB   Input 2.5-5.5V Output 0.6-5V Adjustable DC DC Converter Buck Module       
But this product has the following defects:
1 10-30% rejection rate
2 Difficult to adjust output less than 1.8V
 
     
 
Description: 
 
IC : FP6161 
 
Input voltage DC 2.5~5.5V,Adjustable output 0.6~5.5V
 
Long time maximum output current 1A(5V to 3.3V)
 
Short time maximum output current 1.2A(5V to 3.3V)
 
Low Quiescent current: about 100uA
 
DC-DC Step-Down Converter module working frequency 1.5MHz. efficiency is 75-93% .
 
Size 16.7mm x 10.1mm x 5.5mm(Very small)
 
Weight : about 1g(Very light)
   
LDO Mode
The DD05AJSB’s maximum duty cycle can reach 100% .That means the driver’s main switch is
turn on through out whole clock cycle. Once the duty reaches 100% , the feedback path no longer
controls the output voltage. The output voltage will be the input voltage minus the main switch
voltage drop.
 
Over Current Protection
DD05AJSB limits the peak main switch current cycle by cycle. When over current occurs, chip will
turn off the main switch and turn the synchronous switch on until next cycle.
 
Short Circuit Protection
When the FB pin drops below 300mV, the chip will tri-state the output pin SW automatically. After
300us rest to avoid over heating, chip will re-initiate PWM operation with soft start.
 
Thermal Protection
DD05AJSB will shutdown automatically when the internal junction temperature reaches 150Degrees Celsius to
protect both the part and the system.

Application
Home water tower automatic water supply system
Aquarium Fish tank Water Changer System
Fill the water tower automatically
Automatic pumping from water tower
Conductive liquid automatic control
Automatic feeding system for poultry and livestock
Farm automatic water supply system
And other occasions that require automatic water supply and water exchange.
Solenoid valve water pump motor automatic control
Interface description:
HIGH : Upper limit probe
LOW : Lower limit probe
DC : Power of positive
DC- : Power of negative
NC : Relay normally closed contact
COM : Relay common contact
NO : Relay normally open contact
Working principle(Fill the water tower automatically):
The water level rises: When the water level is lower than the ''Low level'', the water pump starts to supply water to the water tower; when the water level is higher than the ''High level'', the water pump stops supplying water.
Water level reduction: When the water level is lower than the ''High level'', the water pump does not work and the water level continues to decrease. When the water level is lower than the ''Low water level'', the water pump starts to supply water to the water tower.
Working principle(Automatic pumping from water tower):
Contrary to ''Fill the water tower automatically''
Make the probe(Need to be purchased separately):
1 Prepare 2PCS(or more) XH2.54MM wires
(You can prepare this kind of wire by yourself, or buy it from our shop)
2 Multiple wires can be spliced to lengthen the probe length.
(Please do waterproof treatment at the splicing.)
3 Please cut the female interface short and keep a distance of 5-10MM
(This prevents water droplets from sticking to the probe. )
