MAX8790 is producedby MAXIM corporation of U.S.A .MAX8790 is designed for the white driving circuit which uses LED backlighting as the light source array LCD display (LCD) degsign.It uses the current model boost to drive 6 groups of LED and it can provide fixed 20mA or adjustable 15～25mA current to every group of LED.Current is adjusted by stepping control mode, each way current's precision can be controlled between about ±1.5%. AX8790 can use DPWM (digital adjust way) or Analoge stats + DPWM (simulated adjusting mode of linear two ways) to adjust LED brightness。And the regulation range can reach 100∶1.
