AK7864A Product details

Description

 Charge Pump Circuit A necessary voltage for LED (Vf 4.8V or less) lighting is generated from the voltage supplied to VDD pin.Please supply the generated voltage from CPOUT pin to external LED. LED Driver Part This product has 3 channel LED driver to drive RGB constant current.Use the ON/ OFF digital terminal to control the constant current.The current setting can be set to 8 levels (100%/87.5%/75%/62.5%/50%/37.5%/25%/12.5%) with CONT_R/G/B and EN combination.The current of 3 channels

Features

Operating Voltage.
Operating Temperature Range.
LED Driver Current 3.3V±5% 0 ~ 70 C RED: 66mA GREEN: 66mA BLUE: 66mA The LED current is adjustable from 22mA to 66mA by the external resistor. In addition, the LED current can be reduced to 100%~12.5% by the register. Allowable maximum Vf of the LED is 4.8V. The 1/16 watt type is usable to external resistor.
3 chnnel independently ON/OFF (50% setting is an upper bound when 3ch becoming turning on at the same time).
Curre.
