com Description The CP2125E is a step-up DC/DC converter specifically designed for driving white LEDs with a constant current.
The device can drive up to 5 white LEDs from a 3.
0V power supply.
PWM dimming control is supported to adjust the brightness of white LEDs.
The CP2125E switch at 1.
1 MHz, allowing the use of tiny components.
105mV/200mV feedback voltage minimizes the power loss in the current setting resistor for better efficiency.
The CP2125E is equipped with built-in over-voltage protection function, the SW pin monitors the output voltage and will turn of...
