The current of the 4 channels is simply programmed from 20mA to
400mA with an external resistor. The current match between any
channel is ±1.5% (typical). Its operating frequency can be adjusted
from 0.1MHz to 1MHz.

Function
LED current sink 4. Leave the pin open directly if not used.
LED current set pin. The corresponding maximum current of all 4 strings is set through connecting a
resister from this pin to GND.
Overvoltage protection pin. When the OVP pin voltage exceeds 2.0V, the OVP is triggered and the power
switch is turned off. When the OVP pin voltage drops below Hysteresis voltage, the OVP is released and
the power switch will resume normal operation.
Supply input pin. A capacitor (typical 10µF) should be connected between the VIN and GND to keep the
DC input voltage constant.
Analog dimming pin, used in conjunction with DIM. When a DC voltage between 0V and 1.5V is applied
to this pin analog dimming is achieved if DIM is tied HIGH. When a capacitor is connected between this
pin and GND, the PWM signal applied to the DIM pin is filtered and modulates the output current. When
this pin is connected to a HIGH level, direct PWM dimming is achieved.
Soft-start and control loop compensation.

Application Information
Enable
The AL3065 is enabled when the voltage at EN pin is greater than approximately 2.4V, and disabled when lower than 0.5V.
Frequency Selection
An external resistor RT, placed between RT pin and GND, can be used to set the operating frequency. The operating frequency ranges from
NEW PRODUCT
100KHz to 1MHz. The high frequency operation optimizes the regulator for the smallest-sized component application, while low frequency
operation can help to reduce switch loss. The approximate operating frequency can be expressed as below:
f OSC [ MHz ] 
52
RT [ KW]
LED Current Setting
The maximum LED current per channel can be adjusted up to 400mA via ISET pin. When ≥400mA current is needed in application, two or more
channels can be paralleled to provide larger drive current. A resistor RISET is connected between ISET pin and GND to set the reference current
ISET. The LED current can be expressed as below:
I LED [mA] 
1200
RISET [ KW]
Dimming Control
1) Direct PWM Dimming Control
Compared to Analog dimming, PWM dimming offers superior dimming resolution and reduced LED color shift. Tying ADIM to VCC pin enables
direct PWM dimming. The PWM signal is applied to the DIM pin. The LED current of all enabled channels can be adjusted at the same time and
the LED brightness can be adjusted from 1%×ICH_MAX to 100%×ICH_MAX.
During the “high level” period of PWM signal, the LED is turned on and 100% of the current flows through the LED, while during the “low level”
period of the PWM signal, the LED is turned off and almost no current flows through the LED. Changing the average current through the LED can
adjust the LED brightness.
The external PWM signal frequency applied to DIM pin can be 100Hz or higher and the minimum duty PWM duty can be 1/10,000 at 100Hz
dimming frequency.
2) PWM to Analog Dimming Control
When a capacitor is connected between ADIM pin and GND, the IC provides analog dimming function from PWM signal input of DIM pin. The
capacitor forms a filter with the output resistance of ADIM. The output of this filter contains an average DC component thereby modulating the
amplitude of the LED current.
3) DC to Analog Dimming Control
When a DC signal is connected to ADIM pin, the IC provides analog dimming. The amplitude of the LED current can be modified by varying the
ADIM pin voltage between 0V to 1.5V. Tie the DIM pin to logic high level.
Protection
1) Over Voltage Protection
The AL3065 integrates an OVP circuit. The OVP pin is connected to the center tap of voltage-divider (ROV1 and ROV2) connected between high
voltage output and GND.
If the voltage at OVP pin exceeds 2.0V, which may result from open loop or excessive output voltage, all the functions of the AL3065 will be
disabled with output voltage falling. The OVP hysteresis is 200mV.

Application Information (Cont.)
2) Over-Current Protection
The AL3065 integrates an OCP circuit. The CS pin is connected to the voltage-sensor (RCS) placed between the source of the MOSFET and
GND. If the voltage at CS pin exceeds 0.54V, the MOSFET is turned off immediately and will not turn on until the next cycle begins.
NEW PRODUCT
3) LED Short-Circuit Protection
The AL3065 integrates an LED Short-Circuit Protection circuit. If the voltage at any of the CH1 to CH4 pins exceeds a threshold of approximately
7.3V during normal operation, the corresponding channel is latched off. Toggle VIN or EN to reset the latch. LED short detecting logic priority is
lower than open LED and OVP logic. The LED short detecting is triggered when 0.1V < VLED_MIN under dimming on mode, and disabled when
LED open occurs until output voltage resumes to the regulated voltage.
4) LED Open-Circuit Protection
The AL3065 integrates an LED Open-Circuit Protection circuit. When any LED string is open, VOUT will boost up until the voltage at OVP pin
reaches an approximate threshold of 2.0V. The IC will automatically ignore the open string whose corresponding pin voltage is less than 100mV
and the remaining string will continue operation. If all the strings are open and the voltage at OVP pin reaches a threshold of 2.0V, the MOSFET
drive gate will turn off and the IC will shut down and latch.
5) VOUT Short/Open Schottky Diode Protection
The AL3065 monitors the OVP pin, if the OVP pin voltage is less than 0.1V, MOSFET drive output will turn off. This protects the converter if the
output Schottky diode is open or VOUT is shorted to ground.
6) Under-Voltage Lockout
The AL3065 provides an under voltage lockout circuit to prevent it from undefined status when it starts up. The UVLO circuit shuts down the
device when VCC drops below 3.8V. The UVLO circuit has 200mV hysteresis, which means the device starts up again when VCC rises to 4.0V.
7) Over-Temperature Protection
The AL3065 features Over-Temperature Protection. If the junction temperature exceeds approximately +160ºC, the IC will shut down until the
junction temperature is less than approximately +140ºC. When the IC is released from over temperature shutdown, it will start a soft-start process.
8) Schottky Diode/Inductor Short-Circuit Protection
The AL3065 features Schottky Diode/Inductor Short-Circuit protection circuit. When CS pin voltage exceeds 0.8V for greater than 16 switching
clocks, the IC will latch off. The voltage of CS pin is monitored after a short delay of tLEB.
9) Shut Down under Abnormal Condition
The AL3065 features Shutdown under Abnormal Condition Protection circuit. When the OVP pin voltage exceeds 3.2V, the IC will latch off. Toggle
EN pin to restart the IC. This feature can be used to shut down the IC under any defined abnormal condition.
