1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ (MAX), the junction-toambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD (MAX) = (TJ
(MAX)-TA)/θJA. Exceeding the maximum allowable power
dissipation produces an excessive die temperature, causing
the regulator to go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.

MP2410 – 24V, 2A, 1MHZ, SYNCHRONOUS, STEP-DOWN, LED DRIVER
OPERATION
The MP2410 is a high-frequency, synchronous,
rectified, step-down, switching mode LED driver
with a built-in, internal power MOSFET and
synchronous rectifier switch. The MP2410 offers
a very high-performance solution that achieves
up to 2A of continuous output LED current with
excellent load and line regulation over a wide
input supply range.
The MP2410 operates in a fixed 1MHz
frequency and uses peak current control mode
to regulate the output current. A new switching
cycle is initiated by the internal clock at the
beginning of every switching cycle.
The integrated high-side power MOSFET is
turned on, and the inductor current rises linearly
to provide energy to the load. The high-side
power MOSFET remains on until its current
reaches the value of the COMP level, which is
the output of the internal error amplifier. The
output voltage of the error amplifier depends on
the difference of the output feedback and the
internal, high-precision reference.
The high-side power switch remains off until the
next clock cycle begins. After the high-side
switch turns off, the low-side sync switch turns
on, and the inductor current flows through the
low-side switch. To prevent a shoot-through, a
dead time is implemented to prevent the highside and low-side FETs from turning on at the
same time.
When the duty cycle of one switching period
reaches 94%, the current in the high-side power
MOSFET cannot reach the COMP-set current
value, and the high-side power MOSFET is
forced to turn off.
Under-Voltage Lockout (UVLO) and IC StartUp/Shutdown Procedure
Under-voltage lockout (UVLO) is implemented to
prevent the chip from operating at an insufficient
supply voltage. The MP2410 UVLO comparator
monitors the output voltage of the internal
regulator, which is supplied from VIN.
regulator is then enabled. The regulator provides
a stable supply for the remaining circuitries.
Three events can shut down the chip: EN/DIM
low for longer than tOFF_DELAY, VIN drops below
UVLO, and thermal shutdown. In the shutdown
procedure, the signaling path is blocked first to
prevent any fault triggering. The COMP voltage
(VCOMP) and the internal supply rail are then
pulled down.
Error Amplifier (EA)
The internal, low, offset error amplifier compares
the FB voltage with the internal 100mV reference
and outputs a COMP voltage, which is inside of
the chip and is used to control the high-side
MOSFET peak current and regulate the output
current.
Internal Soft Start (SS)
A soft start (SS) is implemented to prevent the
converter output current from overshooting
during start-up. When the chip starts, the internal
circuitry generates a soft-start voltage that ramps
up from 0V. The soft-start period lasts until the
voltage on the soft-start capacitor exceeds the
0.1V reference voltage. At this point, the
reference voltage takes over.
Floating Driver and Bootstrap Charging
The high-side, floating, power MOSFET driver is
powered by an external bootstrap capacitor. The
bootstrap capacitor voltage is regulated
internally. During normal operation, a 5.1V
bootstrap voltage is maintained between BST
and SW.
Enable and Dimming Control (EN/DIM)
EN/DIM is a control pin that turns the regulator
on and off and dims the output LED current
through a DC signal. Leave EN/DIM floating or
drive it high to turn on the MP2410. After
EN/DIM is pulled low for tOFF_DELAY (22ms,
typically), the MP2410 is turned off. Figure 2
shows the control logic of EN/DIM.
If both VIN and EN/DIM are higher than their
appropriate thresholds, the chip starts up. The
reference block starts first to generate stable
reference voltages and currents. The internal

MP2410 – 24V, 2A, 1MHZ, SYNCHRONOUS, STEP-DOWN, LED DRIVER
Open LED
If the LED is open without a feedback signal, the
MP2410 works at the maximum duty cycle, and
the output voltage rises up close to the input
voltage. Every power component operates at a
safe state.
Figure 2: EN/DIM Time Sequence
Analog Dimming
Apply a DC signal on EN/DIM to dim the
MP2410 in analog dimming mode. When the
voltage on EN/DIM is lower than VADIM_MIN, the
LED current is regulated to the minimal scale.
When the voltage on EN/DIM is between
VADIM_MIN and VADIM_MAX, the LED current changes
from the minimal scale to the full scale of the
LED current. If the voltage on EN/DIM is higher
than VADIM_MAX, the maximum LED current is
regulated.
Figure 3 shows the analog dimming curve. Due
to the hysteretic of the EN/DIM on/off threshold,
the chip remains at the minimal LED current
longer at the VEN/DIM falling edge until VEN/DIM is
lower than VEN_OFF. The dimming curve is the
same in the linear dimming range.
LED Short-Circuit Protection (SCP)
The MP2410 integrates LED short-circuit
protection (SCP) circuitry. There are several
features protecting the MP2410 from damage
when an LED short circuit occurs.
The MP2410 features a cycle-by-cycle current
limit to restrict the maximum current of the
inductor. A protection mechanism monitors the
FB level though an internal R-C filter. Once the
FB level rises up to reach VFB_BURST_AL, the chip
stops switching until the FB level drops to a
lower value, and the system works in burst mode.
In the worst-case scenario, the LED is shorted to
GND. If the cycle-by-cycle current-limit function
cannot clamp the current overshoot sufficiently,
then the current through both the high-side and
low-side FETs is also monitored by over-current
detector inside the chip. If this current is higher
than the short-circuit threshold (IOCP), the
MP2410 treats this as a short-circuit condition.
When an over-current condition or short-circuit
condition is detected, the MP2410 turns off both
the high-side and low-side MOSFETs for 2.4ms
and restarts. During this period, VCOMP is pulled
down to ground, so the restart from the fault
condition is also done with a soft start.

Thermal Protection
NTC provides LED thermal protection. An NTC
resistor used to monitor the ambient temperature
can be connected to NTC directly. There is an
internal current source flowing out of NTC. The
corresponding voltage is generated on the
external NTC resistor and the LED current
changes (see Figure 4).

Thermal Shutdown
Thermal shutdown is implemented to prevent the
chip from operating at exceedingly high
temperatures. When the silicon die temperature
is higher than 150°C, OTP shuts down the entire
chip. When the temperature is below its lower
threshold (typically 90°C), the chip restarts.

The NTC resistance value drops when the
ambient temperature rises up. If the NTC voltage
drops below VSD_NTC, the switching stops
completely, and the LED current drops to 0A, so
the LED lamp can be shut down by pulling NTC
down.
Additionally, to protect against any lethal thermal
damage, when the inner temperature exceeds
the OTP threshold, the MP2410 shuts down the
switching cycle with thermal shutdown until the
temperature drops to its lower threshold.

APPLICATION INFORMATION
Selecting the Input Capacitor
Setting the LED Current
A current sense resistor is inserted between the
cathode of LED and GND. The current sense
resistor value can be calculated with Equation
(1):
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 source impedance to prevent the
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 10µF
capacitor is sufficient.

For 2A LED current output, choose RS = 50mΩ.
Selecting the Inductor
An inductor less than 100µH with a nominal DC
current rating at least 25% higher than the
maximum load current is recommended for most
applications. For the highest efficiency, the
inductor’s DC resistance should be less than
100mΩ. For most designs, the required
inductance value can be derived from Equation
(2):
L
VOUT (VIN VOUT )
VIN IL fSW
(2)
Where ∆IL is the inductor ripple current.
Choose the inductor ripple current to be 30% of
the maximum load current. The maximum
inductor peak current can be calculated with
Equation (3):
IL(MAX) ILED

Selecting the Output Capacitor
The output capacitor keeps the output current
ripple small and ensures feedback loop stability.
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 10µF ceramic capacitor is
sufficient.
PCB Layout Guidelines
Efficient PCB layout is critical for stable
operation. For best results, refer to the
guidelines below.
1. Place the high current paths (GND, VIN, and
SW) very close to the device with short,
direct, and wide traces.
2. Place the input capacitor as close to IN and
GND as possible.
3. Place the external feedback resistors next to
FB.
4. Keep the switch node traces short and away
from the feedback network.

evaluation board datasheet.
