Pressure regulation method
The potentiometer faces the chest, counterclockwise to boost!
Maximum Input current: 1A
Maximum output current: 1.4A
Input voltage: 4.5v ~ 8 v
Maximum output voltage:> 4.3V-27 v
Maximum output reference current 5V 1.4A, 9V 0.8A, 12V 0.6A
Quiescent current approx. 0.5 mA
Applicable battery voltage: 3.7V lithium battery
Overshoot protection
Over discharge protection none (or yes, 2V cut-off boost
But the output is not blocked (2V is still available)
Cut off boost voltage 2V, whether additional protection board is added according to the situation
