Boost Type LED Driver with 4-Channel Current Source AP3064
Preliminary Datasheet
General Description
The AP3064 is a high efficiency boost controller with 4-string current sources for driving WLED backlight. It operates over a wide input voltage range from 4.5V to 33V.
The current of 4 strings are simply programmed from 20mA to 220mA with an external resistor. The current matching between each string is 1.5% (Typ). Its operating frequency can be adjusted from 0.1MHz to 1MHz.
The AP3064 features cycle-by-cycle current limit, soft-start, under voltage lockout (UVLO) protection, programmable OVP, over temperature protection (OTP), open/short LED protection, V short/Schottky diode open protection and Schottky Diode short-circuit protection.
The AP3064 is available in SOIC-16, PSOP-16, DIP-16 and QFN-4×4-16 package s.

Function
LED current sink 4. Leave the pin open directly if not used LED current setting pin. The corresponding maximum current of all 4 strings is set through connecting a resistor from this pin to GND Over voltage 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
ON/OFF control pin. Forcing this pin above
2.4V enables the IC while below 0.5V shuts down the IC. When the IC is in shutdown mode, all functions are disabled to decrease the supply current below 3µA

Application Information
1. Enable
The AP3064 is enable when the voltage to EN is greater than approximately 2.4V, disabled when lower than
0.5V.
2. 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 100kHz to 1MHz. The high frequency operation optimizes the r egulator 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:

3. LED Current Setting
The maximum LED current per channel can be adjusted up to 180mA via ISET pin. When ≥180mA current is needed in application, two or more channels can be paralleled to provide larger drive current. Connect a resistor R and GND to set the reference current I current can be expressed as below:

6. Over Voltage Protection
The AP3064 integrates an OVP circuit. The OVP pin is connected to the center tap of voltage-divider (R and R and GND. If the voltage on OVP pin exceeds 2.0V, which may results from open loop or excessive output voltage, all the functions of AP3064 will be disabled with output voltage falling. The OVP hysteresis is 250mV. The formulas of OVP can be expressed as below:

8. LED Short-Circuit Protection
The AP3064 integrates an LED Short-circuit protection circuit. If the voltage at any of the CH1-4 pins exceeds a threshold of approximately 7.3V during normal operation, the corresponding str ing is turned off and is latched off. Toggle V 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<V dimming on mode, disabled when LED open occurs until output voltage resumes to the regulated voltage.

9. LED Open-circuit Protection
The AP3064 integrates an LED Open-circuit Protection circuit. When any LED string is open, V
will boost up until the voltage at OVP pin

reaches an approximate 2.0V threshold. 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 reaches a threshold of 2.0V, the MOSFET drive GATE will turn off and IC will shut down and latch.

The AP3064 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 V
is shorted to ground.

11. Under Voltage Lockout
The AP3064 provides an under voltage lockout circuit to prevent it from undefined status when startup. The UVLO circuit shuts down the device when V 200mV hysteresis, which means the device starts up again when V
drops below 3.6V. The UVLO circuit has

12. Over Temperature Protection
The AP3064 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.
13. Schottky Diode/Inductor Short Cir­cuit Protection
The AP3064 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. The voltage of CS is monitored after a short delay of LEB.
14. Shut Down under Abnormal Cond­ition
The AP3064 features shutdown under abnormal condition protection circuit. When OVP pin voltage exceeds 3.2V, the IC will latch. Toggle EN to restart the IC. This feature can be used for any other protection to shut down the IC.
