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.

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. AL3065 Document number: DS37677 Rev. 1 - 2 10 of 15 www.diodes.com April 2015 © Diodes Incorporated AL3065 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.
