FAN5607 Datasheet Led Driver

Manufacturer: Fairchild (now onsemi)

Overview: www.fairchildsemi.com FAN5607 LED Driver with Adaptive Charge Pump DC/DC.

General Description

The FAN5607 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 Built-in Charge Pump has Three Modes of Operation:.
  • 1X, 1.5X, and 2X Mode Up to 93% Efficiency Low EMI, Low Ripple Up to 120mA Output Current ( 4 × 30 mA ) External Resistor to Se.
