Product details

Description

CP2129 V1.1 DC/DC Series The CP2129 is a step-up DC/DC converter specifically designed for driving white LEDs with a constant current.The device can drive up to 4 white LEDs from a 3V power supply.PWM dimming control is supported to adjust the brightness of the white LEDs.The CP2129 switches at 1.1 MHz allowing the use of tiny components.250mV feedback voltage minimizes the power loss in the current setting resistor for better efficiency.The CP2129 is equipped with the over voltage prote
