Pin Description:
IN+: Power Supply+ (DC 2.5-5V)
IN+: Power Supply-
KEY: Switch(button) port
L+ : LED Output +
L1-: LED Output 1- (Direct output)
L2-: LED Output 2- (Onboard 1.6Ω current limiting resistor)
L3-: LED Output 3- (Onboard 0.8Ω current limiting resistor)
Note: This product has no current limiting function, the maximum load current cannot exceed 1.5A, otherwise the chip will be burned.
LED Drive Current Setting
The LED driving current can be realized by adjusting the value of the current limiting resistor R
The value of resistor R can be adjusted according to the required current:
ILED=(VIN-VF-0.3)/R
(VIN is supply voltage, VF is LED forward voltage)
Example 1 (L2- Port): Power supply voltage 3.8V, VF=3V, R=1.6Ω,
Then ILED=(3.8-3-0.3)/1.6= 0.3125MA
Example 2 (L3- Port):Power supply voltage 3.8V, VF=3V, R=0.8Ω,
Then ILED=(3.8-3-0.3)/0.8= 0.625MA
