Anpec APW7128QA 30v, 1.2mhz, white led driver Datasheet

APW7128
30V, 1.2MHz, White LED Driver
Features
General Description
•
Wide Input Voltage Range from 2.7V to 21V
•
High Current-Limit up to 3.5A
•
0.5V Reference Voltage with ± 3%
The APW7128 is the high power and high efficiency
boost converter with an integrated 30V FET ideal for LCD
panel backlighting applications. 30V output voltage allows for 8 high-power LEDs in series, and 3.5A inductor
current limit allows for more LED strings connected in
parallel. The low 0.5V feedback voltage offers higher
efficiency in WLED driver applications. The wide input
range from 2.7V to 21V made APW7128 a perfect solution for various applications such as LCD monitor and
portable devices. The OVP pin monitors the output voltage to protect IC during open load and FB pin short circuit operations. The APW7128 provides the ALS pin to
simplify the interface to an ambient light sensor for automatic dimming. The APW7128 is available in the thermally enhanced DFN-10 lead 3mm x 3mm package.

Function Description
Output Overvoltage Protection
If the FB pin is shorted to ground or an LED fails open
internal thermal sensor circuit will disable the device
and allow the device to cool down. When the device’s
circuit, output voltage in BOOST mode can increase to
potentially damaging voltages. An optional overvoltage
junction temperature cools by 50°C, the internal thermal
sense circuit will enable the device, resulting in a pulsed
protection circuit can be enabled by connection of the
OVP pin to the output voltage. The device will stop
output during continuous thermal protection. Thermal
protection is designed to protect the IC in the event of
switching if the output voltage exceeds OVP high
threshold and re-start when the output voltage falls
over temperature conditions. For normal operation, the
junction temperature cannot exceed TJ=+125 °C.

Ambient Light Sensor Interface
BP pin. In applications, where the VIN is less than 5.5V,
BP should be tied to VIN through a 10Ω resistor.
The APW7128 provides the ALS pin to simplify the interface to an ambient light sensor. The ambient light sensor detects the ambient light and yields a current which
is related to the illuminance. Connect a load resistor
from the current output of ambient light sensor to ground
to provide an output voltage to ALS pin. The ALS voltage
will be divided by an internal divider circuit, and the divided ALS voltage will replace the internal reference
voltage. The LED current can be calculated by the following equation:
I LED =
1 V ALS
×
3 R2
Note that the maximum FB voltage is set to 0.5V, and
minimum FB voltage is set to 0.2V. If the divided ALS
voltage is over 0.5V or less 0.2V, the LED current is limited at:
ILED (MAX ) =
0 .5 V
R2
ILED (MIN ) =
0 .2 V

where R2 is the resistor from FB to GND.
Enable/Disable
Pull the EN above 2V to enable the device and pull EN
pin below 0.4V to disable the device. In shutdown mode,
the internal control circuits are turned off, the quiescent
current is below 1uA.

Figure 4. Layouy Guidelines
Layout Consideration
The correct PCB layout is important for all switching
converters. If the layout is not carefully done, the regulator
could show stability problems as well as EMI problems.
Figure. 4 illustrates the layout guidelines; the bold lines
indicate these traces that must be short and wide. The
capacitors, the diode, and the inductor should be as close
to the IC as possible. Keep traces short, direct, and wide.
Keep the LX node away from FB and COMP pins. The
trace from diode to the LEDs may be longer. The ground
return of input capacitor and output capacitor should be
tied close to PGND. Use the different ground planes for
signal ground and power ground to minimize the effects
of ground noise. Connect these ground nodes at any place
close to one of the ground pins of the IC. The resistor
from FB to GND should be close to the FB pin as possible.
The metal plate of the bottom must be soldered to the
PCB and connected to LX node and the LX plane on the
backside through several thermal vias to improve heat
dissipation.
