DD05AJSB
Input 2.5-5.5V Output 0.6-5V Adjustable DC DC Converter Buck Module
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 150
Degrees Celsiusto protect both the part and the system.
Attention :
This is a DC-DC voltage converter module,Must be noted when using:
1 Input voltage can not be greater than the maximum input range
2 Output power can not be greater than the maximum load for a long time
3 Input power must be greater than the output power, because the power consumption of the module itself
