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.

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

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

turned off and is latched off. Toggle V

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

OUT

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.

Protection

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.

OUT

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

CC

rise to 3.8V.

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.
