eneral Description The CP2123 is a step-up DC/DC converter specifically designed for driving white LEDs with a constant current. The device can drive up to 33 white LEDs from a 3.5V power supply or 60 white LEDs from a 10-24V power supply. PWM dimming control is supported to adjust the brightness of white LEDs. The CP2123 switch at 1.4 MHz, allowing the use of tiny components. 300mV feedback voltage minimizes the power loss in the current setting resistor for better efficiency.
