Power Return Pin. Connect to the lowest potential in the circuit, which is
typically the anode of the Schottky rectifier. This pin is the voltage reference
for the regulated output voltage. For this reason care must be taken in its
layout. This node should be placed outside of the D1 to C1 & C2 ground path

to prevent switching current spikes from inducing voltage noise into the part.
The exposed pad is also connected to this pin.
Over Voltage Protection Pin. Use a voltage divider to program OVP
threshold. When the OVP pin voltage reaches the shutdown threshold 1.2V,
the switch will be turned off and will recover when OVP voltage decreases
OVP sufficiently. When the OVP pin voltage (with respect to VSS) is lower than
0.4V and FB pin voltage is lower than 0.1V, the chip recognizes this as short
circuit condition and the operating frequency will be folded back. Program the
OVP pin voltage from 0.4V to 1.2V for normal operation.

Frequency Set Pin. Connect a resistor to VSS to set the switching frequency
RSET and a 1nF capacitor to VSS to bypass the noise. Leaving this pin open gets a
default operating frequency 1.35MHz.
On/Off Control Input and Dimming Command Input. A voltage greater than
0.6V will turn on the chip. Both DC and PWM dimming are implemented on
this pin. When the EN/DIM pin voltage (with respect to INGND) rises from
0.7V to 1.4V, the LED current will change from 0% to 100% of the maximum

MPQ2483 –INDUSTRIAL GRADE, 2.5A, 55V, PROGRAMABLE FREQUENCY
OPERATION
The MPQ2483 is a current mode regulator. The
EA output voltage is proportional to the peak
inductor current.
increase in its voltage also increases the
current delivered to the output.
Open LED Protection
At the beginning of a cycle, M1(Fig1) is off. The
EA output voltage is higher than the current
sense amplifier output, and the current
comparator’s output is low. The rising edge of
the 1.35MHz CLK signal sets the RS Flip-Flop.
Its output turns on M1(Fig1) thus connecting the
SW pin and inductor to the input supply.
If the LED is open, there is no voltage on the
FB pin. The duty cycle will increase until OVP-
VSS reaches the shutdown threshold set by the
external resistor divider. The top switch will turn
off till the voltage OVP-VSS decreases
sufficiently.
Dimming Control
The increasing inductor current is sensed and
amplified by the Current Sense Amplifier. Ramp
compensation is summed to the Current Sense
Amplifier output and compared to the Error
Amplifier output by the PWM Comparator.
When the sum of the Current Sense Amplifier
output and the Slope Compensation signal
exceeds the EA output voltage, the RS Flip-
Flop is reset and M1 is turned off. The external
Schottky rectifier diode (D1) conducts the
inductor current.
The MPQ2483 allows both DC and PWM
dimming. When the voltage on EN is less than
0.6V, the chip is turned off. For analog dimming,
when the voltage on EN is from 0.7V to 1.4V,
the LED current will change from 0% to 100%
of the maximum LED current. If the voltage on
EN pin is higher than 1.4V, maximum LED
current will be generated. For PWM dimming,
its amplitude (VDIM – VINGND) must exceed
1.4V. The PWM frequency is recommended in
range of 100Hz to 2kHz to get a good dimming
linearity.
If the sum of the Current Sense Amplifier output
and the Slope Compensation signal does not
exceed the EA output for a whole cycle, then
the falling edge of the CLK resets the Flip-Flop.
Output Short Circuit Protection
The MPQ2483 integrates output short circuit
protection. When the output is shorted to VSS,
the voltage on OVP pin which detects the
output voltage gets smaller than 0.4V, and FB
pin senses no voltage (<0.1V) as no current
goes through the LED. At this condition, the
operating frequency is folded back to decrease
the power consumption.
The output of the Error Amplifier integrates the
voltage difference between the feedback and
the 0.198V reference. The polarity is a FB pin
voltage lower than 0.198V increases the EA
output voltage. Since the EA output voltage is
proportional to the peak inductor current, an

APPLICATION INFORMATION
Setting the LED Current
Where ΔIL is the inductor ripple current.
The external resistor is used to set the
maximum LED current (see the schematic on
front page) through the use of the equation:
Choose the inductor ripple current to be 30% of
the maximum load current. The maximum
inductor peak current is calculated from:
0. 198 V
R
SE NSE

ΔIL
=
IL(MAX) = ILOAD
+
LE D
2
Setting the Operating Frequency
Under light load conditions below 100mA, a
larger inductance is recommended for improved
efficiency.
The resistor on Rset pin is used to set the
operating frequency. A 1nF capacitor is
recommended to bypass this pin to GND.
Also note that the maximum recommended load
current is 2A if the duty cycle exceeds 35%.
The relationship between the operating
frequency and the Rest resistor is as the
following curve. A 20kΩ to 200kΩ Rset resistor
is recommended, which sets the operating
frequency from around 1.35MHz to 250 kHz.
Leaving the RSET pin open will set the
operating frequency to the default operating
frequency 1.35MHz.
Selecting the Input Capacitor
The input capacitor reduces the surge current
drawn from the input supply and the switching
noise from the device. The input capacitor
impedance at the switching frequency should
be less than the input source impedance to
prevent high frequency switching current from
passing through the input. Ceramic capacitors
with X5R or X7R dielectrics are highly
recommended because of their low ESR and
small temperature coefficients. For most
applications, a 4.7µF capacitor is sufficient.
Selecting the Output Capacitor
The output capacitor keeps the output voltage
ripple small and ensures feedback loop stable.
The output capacitor impedance should be low
at the switching frequency. Ceramic capacitors
with X5R or X7R dielectrics are recommended
for their low ESR characteristics. For most
applications, a 2.2µF ceramic capacitor will be
sufficient.
Selecting VSS-INGND Positive Spike
Protection Circuit
Selecting the Inductor
(Step-Down Applications, see Figure 3)
In some applications, such as input power on,
LED+ short circuit from LED+ to VSS in both
Buck-Boost and Boost applications, when
INGND and VSS are not connected together,
there is potential risk that VSS-INGND has
>0.3V (allowed maximum positive voltage)
positive spike, which might cause false actions,
even damage.
A 1µH to 47µH inductor with a DC current rating
of at least 25% percent higher than the
maximum load current is recommended for
most applications. For high efficiency, the
inductor’s DC resistance should be less than
200mꢀ. Refer to Table 2 for suggested surface
mount inductors. For most designs, the required
inductance value can be derived from the
following equation.

VIN × ΔIL × fSW

MPQ2483 –INDUSTRIAL GRADE, 2.5A, 55V, PROGRAMABLE FREQUENCY
To clamp VSS-INGND positive spike, it is
PC Board Layout
recommended to add a 100ꢀ resistor from
INGND pin to input GND to clamp the current
from VSS to INGND, and to add a low forward
voltage schottky diode (B160) from VSS to
INGND to clamp the negative oscillation voltage.
The voltage rating of the schottky diode should
be higher than the OVP voltage set by R3 and
R4 (Figure 5).
The high current paths (VSS, VDD and SW)
should be placed very close to the device with
short, direct and wide traces. The input capacitor
needs to be as close as possible to the VDD and
VSS pins. The external feedback resistors should
be placed next to the FB pin. Keep the switch
node traces short and away from the feedback
network.
To extremely high VSS-INGND spike conditions,
bigger R2 is needed to clamp the current, and
higher current rating D2 is needed too.
Figure 2: VSS-INGND Positive Spike
Protection Circuit
Selecting FB Positive Spike Protection Circuit
In applications when there is possibility that FB
has abnormal high positive spike, such as Load
transients from high to low or LED+ short circuit
from LED+ to LED- in Buck, Boost and Buck-
Boost applications. In applications above, once
FB has abnormal high positive spike, false
actions, even damage might happen.
To protect FB from too high positive spike, it is
recommended to add a 10kohm resistor between
LED- to FB to clamp the current from LED- to FB,
and to add a <2V voltage range zener diode
(BZT52C2V0) from FB to VSS to clamp the
voltage from FB to VSS.
