2.8-6V 30-1500MA 1.5A LED Driver PWM Control Board Module Adjustable Cons
Description:
LD06AJSA/B is a constant current integrated circuit that operates with input voltage of 2.8V to 6V, and can be set to 1.5A by external resistor. LD06AJSA/B consists of high precision standard voltage, amplifier, current mirror, etc. On-chip power transistors and current block sense greatly reduce the number of external components, making it ideal for LED drivers.
If the pin is high, the input voltage exceeds 2.8V, higher than the required voltage drop of the LED DC voltage, and LD06AJSA / B operates normally and provides constant current from PULLOBEE LD06AJSA / B adopts temperature control instead of temperature protection Due to temperature control, LEVOU may be continuously turned on if ambient temperature is high or high voltage drop. When the junction temperature of LD06AJSA/B reaches about °C, the current will be reduced by the internal temperature setting of the block to prevent the LED junction from rising any more. This feature allows users to maximize the power handling capability of the chip, eliminating the need to worry about overheating the chip or damage to the chip or external components.
LD06AJSA/B also has a function that can limit the current consumption when the chip is shut down within 1uA.
LD06AJSA/B also adopts current overload protection blocks. When the LED current is close to 1.9A (Typical), the protective current block starts to function and prevents the LED current from increasing.
Application 1: Follow the following diagram and carefully use the appropriate screwdriver to slowly rotate the adjustable resistance.
