The CAT3649 is a high efficiency Quad−Mode® fractional charge
pump that can drive up to six LEDs. The inclusion of a 1.33x fractional
charge pump mode increases the device efficiency by up to 10% over
traditional 1.5x charge pumps with no added external capacitors.
Low noise input ripple is achieved by operating at a constant
switching frequency which allows the use of small external ceramic
capacitors. The multi−fractional charge pump supports a wide range of
input voltages from 2.4 V to 5.5 V.
The LED current can be adjusted in different ways. The full−scale LED
current is set to 25 mA once the device is enabled. Analog dimming in
32 linear steps is achieved via a 1−wire pulse−dimming input (ADIM).
Further adjustment of the LED current can be done by applying a pulse
width modulation (PWM) signal on the PWM input. The PWM
dimming control is compatible with content adaptive brightness control
(CABC) for a wide range of PWM signal frequency up to 200 kHz.
The CAT3649 can be shut down by holding the ADIM or PWM
input in a logic low condition for greater than 30 ms.
ON Semiconductor’s Quad−Mode 1.33x charge pump switching
architecture is patented.

Figure 3. Functional Block Diagram
Basic Operation
This sequence repeats in the 1.33x and 1.5x mode until the
driver enters the 2x mode. In 1.5x mode, the output voltage
is approximately equal to 1.5 times the input supply voltage.
While in 2x mode, the output is approximately equal to 2
times the input supply voltage.
If the device detects a sufficient input voltage is present to
drive all LED currents in 1x mode, it will change
automatically back to 1x mode. This only applies for
changing back to the 1x mode. The difference between the
input voltage when exiting 1x mode and returning to 1x
mode is called the 1x mode transition hysteresis (VHYS) and
is about 300 mV.
At power−up, the CAT3649 starts operating in 1x mode
where the output will be approximately equal to the input
supply voltage (less any internal voltage losses). If the
output voltage is sufficient to regulate all LED currents, the
device remains in 1x operating mode.
If the input voltage is insufficient or falls to a level where
the regulated currents cannot be maintained, the device
automatically switches into 1.33x mode. In 1.33x mode, the
output voltage is approximately equal to 1.33 times the input
supply voltage (less any internal voltage losses).

PIN FUNCTION
VOUT is the charge pump output that is connected to the
LED anodes. A small 1 mF ceramic bypass capacitor is
required between the VOUT pin and ground near the device.
GND is the ground reference for the charge pump. The pin
must be connected to the ground plane on the PCB.
C1+, C1− are connected to each side of the ceramic bucket
capacitor C1.
C2+, C2− are connected to each side of the ceramic bucket
capacitor C2.
LED1 to LED6 provide the internal regulated current
source for each of the LED cathodes. These pins enter
high−impedance zero current state whenever the device is
placed in shutdown mode.
TAB is the exposed pad underneath the package. For best
thermal performance, the tab should be soldered to the PCB
and connected to the ground plane.
CPWM is the pin for connecting an external capacitor used
to filter the PWM signal inside the CAT3649.
VIN is the supply pin for the charge pump. A small 1 mF
ceramic bypass capacitor is required between the VIN pin
and ground near the device. The operating input voltage
range is from 2.4 V to 5.5 V. Whenever the input supply falls
below the under−voltage threshold (1.8 V), all the LED
channels are disabled and the device enters shutdown mode.
ADIM is the one wire dimming input for all LED channels.
Levels of logic high and logic low are set at 1.3 V and 0.4 V
respectively. When ADIM first transitions from low to high,
each LED channel current is set to 25 mA. Each subsequent
pulse will decrement the current by about 3% from the full
scale.
PWM is the pulse width modulation input pin. When in
logic high condition, the LED current in all six channels
equals the programmed level set via ADIM. When PWM is
low, the LED current is set to 0 mA. This allows the average
LED current to be programmed by the PWM duty cycle. To
place the device into “zero current” shutdown mode, the
ADIM or PWM pin must be held low for 20 ms typical.

Current Selection
Table 6. DIMMING LEVELS
After power−up and once enabled, the LED current is set
initially to the full scale of 25 mA. The number of pulses (n)
on the ADIM input decreases the current value as follows:

(eq. 1)
The full scale current is calculated from the above formula
with n equal to zero.
The ADIM pin has two primary functions. One function
enables and disables the device. The other function is LED
current dimming with 32 different levels by pulsing the input
signal, as shown on Figure 28. On each consecutive pulse
rising edge, the LED current is decreased by about 3.1%
(1/32th of the full scale value). After 31 pulses, the LED
current is 3.1% of the full scale current (lowest level). On the
following pulse, the LED current goes back to full scale.
Each pulse width should be between 200 ns and 100 ms.
Pulses faster than the minimum TLO may be ignored and
filtered by the device. Pulses longer than the maximum TLO
may shutdown the device. By pulsing the ADIM signal at
high frequency, the LED current can quickly be set to zero.
The LED driver enters a “zero current” shutdown mode if
ADIM is held low for longer than 30 ms.
The dimming level is set by the number of pulses on the
ADIM after the power−up, as shown in Table 6.

Figure 28. ADIM Dimming Timing Diagram (no CPWM, PWM high)
CPWM Filtering Capacitor
f PWM w 40
The PWM input signal controls the LED current
proportionally to its duty cycle. When the LED driver
operates in PWM dimming mode, the CPWM capacitor
minimizes the LED current ripple. This prevents audio noise
from the LED driver output capacitors as the PWM signal is
converted into a near DC current internally. The PWM input
is a logic input and the amplitude of the PWM signal does
not affect the LED current. An internal 4 mA current source
is charging the CPWM capacitor when the PWM input is high
until it reaches a maximum voltage; see Figure 29 block
diagram. The internal resistor R (150 kW) and external
capacitor CPWM act as a low pass filter with a cut−off
frequency fC = 1 / 2π R CPWM.
To minimize the ripple current, we recommend the PWM
frequency fPWM to be at least 40 times greater than the
cut−off frequency fC:
C PWM w

(eq. 4)
We recommend a 47 nF capacitor CPWM compatible for
any PWM frequency between 1 kHz and 200 kHz. For PWM
frequency below 1 kHz, the above formula will provide the
recommended capacitor value.
The CPWM capacitor affects the power−up time which is
the time to reach the nominal LED current. The power−up
time (tPU) is proportional to the CPWM capacitor value and
can be calculated as follows.

Unused LED Channels
SHORT LED Detection
For applications with five LEDs or less, it is required to tie
the unused LED pin(s) directly to VOUT (see Figure 30).
If the LED forward voltage (VF = VOUT – LED pin
voltage) is less than 1 V, the channel is disabled and removed
from signaling charge pump mode changes. A 5 mA (typical)
test current is placed in the (shorted) channel. In case the
LED short goes away and VF is higher than 1 V, the channel
resumes normal operation.

Thermal Protection
If the die temperature exceeds +150°C, the driver will
enter a thermal protection shutdown mode. When the device
temperature drops by about 20°C, the device will resume
normal operation.

LED Selection
LEDs with forward voltages (VF) ranging from 1.3 V to
3.8 V may be used. Selecting LEDs with lower VF is
recommended in order to keep the driver in 1x mode longer
as the battery voltage decreases. For example, if a white
LED with a 3.3 V VF is selected over one with 3.5 V VF, the
driver will stay in 1x mode for lower supply voltage of 0.2 V.
This extends battery life.
47 nF
Figure 30. Application with 5 LEDs
Protection Modes
As soon as the output voltage (VOUT) exceeds about 6 V,
the driver resets itself and re−evaluates the mode.
The driver supports automatic LED detection for both
Open LED and Short LED conditions. This feature disables
any unused channels (by connecting the LED pins to
VOUT) or during an LED Short condition. The LED
detection is always active, during power−up and in normal
operation.
External Components
The driver requires four external 1 mF ceramic capacitors
for decoupling input, output, and for the charge pump. Both
capacitors type X5R and X7R are recommended for the
LED driver application. In all charge pump modes, the input
current ripple is kept very low by design and an input bypass
capacitor of 1 mF is sufficient.
In 1x mode, the device operates in linear mode and does
not introduce switching noise back onto the supply.
OPEN LED Detection
When an LED channel becomes open−circuit, the device
will go into charge pump mode and drive the output (VOUT)
above 4.5 V. If that channel is still not working at VOUT
greater than 4.5 V, the channel is locked out from signaling
a charge pump mode change and the device returns to
normal operation like a 5−channel device. If an Open LED
condition is removed, the device will resume normal
operation.
Recommended Layout
In charge pump mode, the driver switches internally at a
high frequency. It is recommended to minimize trace length
to all four capacitors. A ground plane should cover the area
under the driver IC as well as the bypass capacitors. Short
connection to ground on capacitors CIN and COUT can be
implemented with the use of multiple via. A copper area
matching the TQFN exposed pad (TAB) must be connected
to the ground plane underneath. The use of multiple via
improves the package heat dissipation.
