GENERAL DESCRIPTION
PWM dimming control is supported to adjust the brightness of white LEDs. 300mV feedback voltage minimizes the power loss in the current setting resistor for better efficiency. The CP2123 is equipped with over-voltage protection function, the OVP pin monitors the output voltage and will turn off the device if an over-voltage condition is present to prevent damage from an open circuit condition. The CP2123 is available in SOT23-6L and DFN-8L package. FEATURES
Inherently matched LED current High efficiency: Up to 90% Over-voltage protection with linear OVP voltage setting Fast 1.4 MHz switching frequency Shutdown current: <1μA SOT23-6L and DFN-8L package Up to 1MHz PWM Dimming Drives up to 12 series connected LEDs from a 3.5V power supply Drives up to 33(11×3) LEDs from a 3.5V power supply Drives up to 60 LEDs from a 10V power supply APPLICATIONS
