AK7864A - 3 channel LED driver

Datasheet Summary

Description

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.

This product has 3 channel LED driver to drive RGB constant current.

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.

[AK7864A] AK7864A 3 channel LED driver with Charge Pump Device Outline This product includes the charge pump power supply and the 3 channel LED driver who drives the LED of the anode common in the constant current. The current to pass for each channel can be adjusted by the external resistance and the register setting. Also, it has the control pins which turn on or off the current. It is the suitable for the LED drive for the CIS sensor.
