Application 2: Adjust the adjustable resistance to 0 ohms (or maximize the current according to Application 1) and then use the MCU output PWM signal to control the LED output current
When the EN pin is high, the input voltage is greater than 2.9V, and is larger than the LED forward voltage plus the required voltage drop, LD1500SB functions normally to deliver constant current from the LED pin.
The LD1500SB adopts the temperature regulation instead of temperature protection function, the temperature regulation can make the LED being turned on continuously in case of high ambient temperature or high voltage drop. When the LD1500SB junction temperature reaches about 135 ° C, the internal temperature regulation block reduces the LED current so that the junction temperature will not rise any more. This feature allows the users to maximize the use of the power handling capability of the chip, do not worry about the chip overheating and damage to the chip or external components.
The LD1500SB also has the chip enable function, which can shutdown the whole chip to limit the current consumption within 1uA.
The LD1500SB also adopts the over current protection block. When LED current approaches 0.9A(Typical), the over current protection block begins to function to prevent the LED current from increasing further.
* Delivery Time.
We need 1-2 days to process your order before shipping.There are two shipping methoed. Fast Delivery: The delivery time for US, European countries the delivery will take 3-5 days.Slow Delivery: The delivery time for US, European countries the delivery will take 10-15 days.
* Tracking information.
After we ship package, customer receive automatic email with tracking details.
* Lost Package Policy.
If a package did not arrive in 4 weeks after the shipping date, then this package is treated as Lost. In this case a new package will be shipped to the customer provided we are able to give the same items as those purchased by the customer. If we are not able to provide the same items to substitute the lost ones we will either propose to the customer similar items or refund their cost as it will be mutually agree with the customer. If one or more items neither the same nor similar are available to be shipped, the customer can request to cancel the order entirely, thus the total cost of the order including shipping and handling cost will be fully refunded.
