LED-1W1P is a pulse output LED driver module with pump boosting scheme. It has the simplest circuit structure, the lowest production cost, the smallest volume, the highest conversion efficiency, and the convenience of a 10K potentiometer. 0—100% continuous pulse width dimming. Normal working voltage is 0.8-1.8V, starting voltage is 0.6V, fully extinguished voltage is lower than 0.35V. Maximum output power is 1W. It can be used to drive a 350mA 1W high power LED Or drive 18 20mA low-power LEDs in parallel. This module is not a precision control device, the battery voltage will reduce the output power.
The module has 5 lead pins, positive power supply, negative power supply, output pin, and two dimming control pins. The positive pole of the LED is connected to the output pin, the negative pole is connected to the negative pole of the power supply, and a 10K potentiometer is connected between the control poles for dimming. No dimming is required, and the two control legs can be directly connected. The module has a circular structure. The volume is: Φ14.5×13mm.
This type of module must not be energized at no load, otherwise it may be damaged.
LED-3W6D is a pump-type boost DC output LED driver module with input voltage of 6V, maximum output voltage of 12V, output power of 4 watts, output current of 350mA, and can drive 1 to 3 1 watt high power LEDs. Module There are 5 pins, power supply positive, power supply negative, output positive, output negative, control pin. Module volume 30×18×16mm.
The module has strong functions, the output has a current limiting function, and the input has a low voltage cut-off function to protect the battery from over-discharge. The control terminal can accept external light control and remote control signals to realize controlled switching.
