PRODUCT SPECIFICATION

REV. 1.0.4 6/4/04
In some cases, there is already a voltage bus in the system,
which can be utilized. Due to the ultra-low voltage drop of
the FAN561X series of LED drivers to drive high VF white
or blue LEDs. The VIN needs to be only 300mV higher than
the highest VF in the circuit.
–VDROP < 0.3V
–VF (at 20mA) < 3.3V to 4.0V (High VF)
–VIN (at 20mA) =VDROP + VF = 3.6V to 4.3V
–VIN (at 5mA Typical) ~ 3.3V
Where VIN = Existing bus = 3.3V to 4.3V
Key advantages:
• No boost circuit needed for LCD or keyboard backlight
• Driver utilizes the existing bus
• Ultra-low voltage drop provides the full 20mA LED
current at the lowest possible voltage level.
Example 3: Drive white, blue, red, amber LEDs
string
Assuming boost circuit, or existing voltage bus, the
FAN561X series of LED drivers can be used to drive a whole
string of LEDs and flexible brightness control - analog
and/or PWM.
–VDROP < 0.3V
–VIN_MIN = N
× VF + VDROP
–VIN _MAX = N
× VF + 5.5V
Where VIN = Existing bus, boost voltage
Key advantage:
• No need for current matching resistors and discrete
transistor for brightness control
LED Brightness Control
All of the FAN561X LED Drivers feature analog and PWM
controls to give designers flexible brightness control. These
control methods can be applied to the circuit in two different
ways, to provide more flexibility than any other solution. To
determine the value of RSET, use the “ISET vs. VCTRL” graph
under the Typical Performance Characteristics section.
1. FAN5611
- Analog
Set VCONTROL and RSET for LED current
- PWM
VCONTROL = PWM
– Amplitude sets maximum LED current
– Pulse width controls between 0 and maximum
2. FAN5612
- Analog
Set VCONTROL and RSET for LED current
- PWM - 1
VCONTROL = PWM
