Application Information

VCC and VDD Regulators
The MSL1060 includes two linear voltage regulators to
generate the internal voltage rails, VDD and VCC. The
regulators allow the same higher voltage supply, VIN,
which supplies the LED boost regulator to power the
MSL1060 internal circuity. Only use the VDD and VCC
regulators to power the MSL1060’s internal circuitry; do
not draw any external current from the regulators.
The VCC regulator generates a 6V rail from VIN. VCC
powers the boost regulator’s power switch and the
VDD regulator. Bypass VCC to GND either with a 10μF
or greater ceramic capacitor or with a 10μF or greater
tantalum capacitor in parallel with a 1μF ceramic capacitor.
In applications where there is a local 4.75V to 6.5V supply
available, power VCC powered directly from this supply
by connecting VCC and VIN together to this 4.75V to 6.5V
supply. A higher voltage supply can still be used to power
the LED boost regulator by applying the voltage to the
inductor, L1 (Figure 16), and not the MSL1060.
The VDD regulator generates a 2.85V rail from VCC.
VDD operates the internal low-voltage circuits. Bypass
VDD to GND with a 1μF or greater capacitor.
Internal Oscillator - R4
Set the MSL1060 internal oscillator frequency with
resistor R4 from OSC to GND (Figure 16). Use a 115k ?
±1% resistor for R4, which also sets the boost regulator
PWM frequency to 1.1MHz. Changing the internal
oscillator frequency alters the boost regulator internal
frequency compensation degrading performance. Do
Setting the Full-scale LED String Current - R5
Set the full-scale static LED current for all enabled
strings with the resistor, R5 (Figure 16), from ILED to
GND. The maximum full-scale LED current is 30mA.
Calculate the resistor R5 value to set the full-scale LED
string current I ILED by the equation:
2000
R 5
where R5 is in kilohms and ILED is in milliamperes.
Resistor R5 value of 100k ? sets the full-scale LED
current to 20mA. Use R5 value not less than 66.7k ? ,
which sets the full-scale LED current to 30mA.
Enable Input - R7
The EN input turns on/off the MSL1060. Drive EN high
(or connect to VIN through resistor R7) to turn on the
MSL1060, and drive EN low to turn it off. The EN input
is internally over-voltage protected (Figure 17) to allow
connection to a higher voltage than the 8V maximum
input voltage rating by use of an ESD clamp at the input,
which sinks current if the input exceeds typically 12V.
An internal 10.5k ? series resistor followed by a 5.8V
Zener diode further limits the voltage to the internal
logic buffer. Use an external series resistor, R7 to limit
the ESD clamp current to no more than 20mA If EN
is driven to a voltage higher than 8V. Use R7 value of
100k ? when driving EN high to voltages above 8V, and
omit R7 (directly drive EN) for voltages below 8V.
not use a different value for R4, or else the MSL1060
performance is not guaranteed.
