FAN5609 Datasheet Led Driver With Adaptive Charge Pump DC/dc Converter

Manufacturer: Fairchild (now onsemi)

Overview: .fairchildsemi. FAN5609 LED Driver with Adaptive Charge Pump DC/DC.

General Description

The FAN5609 generates regulated output current from a battery with input voltage varying between 2.7V to 5.5V.

Switch reconfiguration and fractional switching techniques are utilized to achieve high efficiency over the entire input voltage range.

A proprietary internal circuitry continuously monitors each LED current loop and automatically adjusts the generated output DC voltage to the lowest minimum value required by the LED having the highest forward voltage.

Key Features

  • Parallel LED Driver Supports All Forward Voltages Adaptive VOUT Adjustment to the Highest Diode Voltage Internally Matched LED Current Sources No External Components Needed to Set LED Current Built-in Charge Pump has Three Modes of Operation:.
  • Linear Regulation VIN > 4.2V.
  • 3/2 DC-DC Converter and Regulation 3.6V.
