LD06AJSB DC 2.8-6V 30-1500mA Constant Current Converter Adjustable Control Module PWM Controller Board for 3V 3.3V 3.7V

Specifications Working voltage DC 2 8 6VOutput Current 31 1500mAMaximum output power 9W Can drive 1 16pcs 2 8 6V LEDs maximum current does not exceed 1 5A Perfect for 3V 3 3V 3 7V 5V 6V LED Driver Current regulation 1 through adjustable resistance 2 through PWM control Chip Temperature RegulationOver LED Current Protection Size 18mm x 10 2mm x 2 8mm Application Application 1 Wiring in accordance with the following figure use a suitable screwdriver gently and slowly rotate the adjustable resistance 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 currentthe frequency of the PWM signal should be less than 2KHz Overview 1 LD06AJSA B is a current regulation integrated circuit operating from an input voltage of 2 8V to 6V the constant output current can be set up to 1 5A with an external resistor The LD06AJSA B consists of high precision reference voltage amplifier current mirror etc The on chip power transistor and current sense block greatly reduce the external component count which makes the LD06AJSA B ideal for LED driver When the CE pin is high the input voltage is greater than 2 8V and is larger than the LED forward voltage plus the required voltage drop LD06AJSA B functions normally to deliver constant current from the LED pin 2 The LD06AJSA B adopts the temperature regulation instead of temperature protection
