General Description

The APW7000 is a high efficiency charge pump white

LED driver; the device drives up to four white LEDs with

regulated constant current for uniform intensity. The sup-

ply voltage ranges from 2.7V to 5.5V and it is optimized for

a Li-ion battery application. The APW7000 operates in 1x,

1.5x, and 2x charge pump modes and automatically

switches the charge pump modes depend on the input

voltage to maintain the required power for high power

efficiency. The APW7000 provides up to 30mA per LED,

for a total of 120mA and allows several methods such as

a PWM signal on the CTRL0 pin for LED dimming. Three

control logic pins allow to disable or enable a combina-

tion of LEDs. The supply current is only 2mA in 2x mode,

and the EN pin allows the device to enter shutdown mode

with 2µA quiescent current. The APW7000 switches at

1MHz frequency and only requires four 1µF ceramic ca-

pacitors and one resistor, and ensures low input current

ripple and EMI.

The APW7000 is available in a 16-pin QFN package.

Ordering and Marking Information

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which

are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C for

MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen

Function Description

Soft-Start

The APW7000 provides the soft-start function to limit the

inrush current during startup. When the input voltage is

supplied to the device and exceeds the UVLO voltage,

the output capacitor is charged directly from input with a

limited current source. Approximate 100µs after the out-

put voltage approaches the input voltage, the device starts

to provide the programmed LED current and determines

which of 1x, and 1.5x, or 2x mode is required. When the

programmed LED current can be reached with 1x mode,

the soft-start is completed and the device operates in 1x

mode. When the programmed LED current cannot be

reached, the charge pump goes into 1.5x mode. If the

1.5x mode charge pump cannot suffice for the LED cur-

rent need, the charge pump will switch to 2x mode.

Mode Transition

The APW7000 operates in 1x, 1.5x and 2x charge pump

modes and automatically switches the charge pump

modes depend on the input voltage to main tain the re-

quired power for high power efficiency. If the APW7000

operates in 1x mode, the VOUT is pulled up to VIN. When

VIN decreases, the VILED will decease to maintain the

regulated LED current. Until VILED is below 100mV, the

device will switch to 1.5x mode. In 1.5x mode, the VILED

is regulated to 0.18V, and the output voltage is VF+0.18V.

If VIN continues to decrease until VILED is below 100mV

again, the device will switch to 2x mode. When the VIN

rises and reaches by approximately VOUT-300mV, the

APW7000 switches back to 1.5x mode. If the VIN contin-

ues to rise and reaches by approximately VOUT+300mV,

the APW7000 switches back to 1x mode. The 2x charge

pump is enough to suffice the White LED for a Li-ion

battery application. The APW7000 ensures that in the 1x

mode for as long as possible to increase the efficiency

and extend the operating range by using the 2x mode.

The transition voltages from 1x to 1.5x and 1.5x to 2x are

given by:

VTRANS1X = VF + 0.1V + (IOUT x ROUT1X)

VTRANS1.5X = [VF + 0.1V + (IOUT x ROUT1.5X)] / 1.5

where VF is the forward voltage of LED

IOUT is the output current

ROUT1X is the output impedance in 1x mode = 1.6Ω

ROUT1.5X is the output impedance in 1.5x mode = 7Ω

Control Logic Pins

The APW7000 provides three logic input pins to enable

or disable a combination of LEDs. Table1 shows the truth

table of the logic pins. If the LED channels are not used,

connecting the ILED pins to VOUT to turn off the respec-

tive LED channels.

Shutdown/Enable

Pull the EN above 1.3V to enable the device and pull EN

pin below 0.3V to disable the device. In shutdown mode,

all internal control circuits are turned off and the quies-

cent current is below 2µA. When the device exits shut-

down mode, the output has soft-start function as the in-

put voltage startup.

Over-Voltage Protection

If any of LEDs is failed or unused LED channel is not

connected to the VOUT, the charge pump mode will go

into 2x mode and the output voltage will be pumped to 2

times the input voltage. If the output voltage is over 5.5V,

the over-voltage protection circuit will limit the output volt-

age to approximately 5.5V.

Application Information

Capacitor Selection

For lower input and output voltage ripples, both input and

output capacitors should be larger values and lower ESR

capacitors. However, the larger output capacitor values

will increase the soft-start time. The lower charge pump

flying capacitors values and ESR improve the efficiency,

but lower capacitor values may limit the LED’s currents at

low input voltage.

It is recommended that the low ESR and low variation

over temperature, such as the ceramic capacitors with

X7R or X5R and the value is 1µF for the input capacitor,

output capacitor, and the charge pump flying capacitors.

Brightness Control

1. PWM dimming using CTRL0, CTRL1, CTRL2

The first method for dimming the LEDs is to apply a PWM

signal into the CTRL0, CTRL1, and CTRL2 pins. Figure2

shows the application circuit. The average LED current is

proportional to the PWM signal duty cycle. Note that the

frequency of PWM signal will affect the minimum dim-

ming duty. Figure3 shows the LED current vs. dimming

frequency and dimming duty, the recommend dimming

frequency is below 10kHz. The average LED current is

calculated by the following equation:

Where:

ILED(max) is programmed LED current by ISET pin

toff is the off time of the PWM signal

ton is the on time of the PWM signal

2. Analog dimming with analog voltage

The second method for dimming the LEDs is to apply a

voltage through a resistor into the ISET pin. The variation

of LED current is proportional to the variation of the ana-

log voltage. If the resistor values are chosen correctly, the

analog control voltage varies the output current from 0mA

to full LED current. Figure 4 shows the application circuit.

See the table2 and choose the required maximum LED

current and the corresponsive RSET value, using the be-

low equation to calculate the values of R1 and R2, note

that the VADJ will need to be greater than 1.2V.

Where: VISET = 1.2V

VADJ = the analog voltage for dimming the LEDs

RSET = the equivalent RSET resistance (see table 2).

3. Digital dimming with external NMOS transistors

The third method for dimming the LEDs is to change the

equivalent resistance for RSET with the external NMOS

transistors. The equivalent resistance is the parallel

combinations of the R1, R2, R3, and R4. R4 is always

connected and selected for the minimum LED current.

Figure 5 shows the application circuit.

4. PWM dimming with EN pin

Another method for dimming the LEDs is to apply a PWM

signal into the EN pin. The average LED current is pro-

portional to the PWM signal duty cycle. Note that the fre-

quency of PWM signal will affect the minimum dimming

duty. The recommend dimming frequency is between

100Hz and 1kHz. The average LED current is calculated

by the following equation:

Where:

ILED(max) is programmed LED current by ISET pin

toff is the off time of the PWM signal

ton is the on time of the PWM signal

Layout Consideration

The APW7000 is a high frequency charge pump for white

LED driver and requires some care when laying out the

printed circuit board. The metal GND pad of the bottom of

the package must be soldered to the PCB and connected

to the GND plane on the backside through several ther-

mal vias. Place the CIN, COUT, C1, and C2 as close to IC

as possible for reducing the switching noise.
