Product Brief CP2125E V0.9 DC/DC Series Step-Up White-LED Driver with Built-in Over-voltage Protection General www.datasheet4u.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.
