FAN5608 Datasheet Serial/parallel Led Driver

Manufacturer: Fairchild (now onsemi)

Overview: www.fairchildsemi.com FAN5608 Serial/Parallel LED Driver with Current-Regulated, Step-Up DC/DC.

General Description

The FAN5608 LED driver generates regulated output currents from a battery with input voltage varying between 2.7V to 5V.

An internal NMOS switch drives an external inductor, and a Schottky diode delivers the inductor’s stored energy to the load.

Proprietary internal circuitry continuously monitors the currrent on both strings and automatically adjusts the generated output DC voltage to the lowest minimum value required by the LEDs string with the highest summarized forward voltage.

Key Features

  • Two Independent Channels Drive up to Six LEDs per Channel.
  • Adaptive Output Voltage Drive to Maximize Efficiency.
  • PWM/PFM Mode of Operation of the Boost Circuit.
  • Up to 85% Efficiency.
  • Up to 2 × 20mA Output.
  • Two Built-in DACs for Independent (Digital) Brightness Control for Both Channels.
  • LED’s Current Can be Duty-Cycle-Modulated between 0 to 20mA.
  • Digital, Analog, and PWM Brightness Control.
  • 2.7V to 5V Input Voltage R.
