A constant current step-up converter with internal NMOS and allows series connection of the white LEDs. The output current of each channel can be set by an external resistor and dimming the brightness of LEDs with the PWM signal or DC voltage
Adjustable linear current devices with excellent temperature stability and can drive LED strings close to the supply voltage without switch capacitors or inductors.
150mA Dual channel which can be combined to provide a total of 300mA linear programmable LED driber with fault detection, featuring ENx pins to independently adjust the average output
36 constant current channels, each channel can be pulse width modulated (PWM) by total 8 bits+10 bits (261890 steps) for smooth LED brightness control or color mixing control
