CAT3636
6-Channel Quad-Mode[
Fractional LED Driver in
TQFN 3x3
Description
http://onsemi.com
The CAT3636 is a high efficiency Quad−Mode fractional charge
pump that can drive up to six LEDs programmable by a one wire
digital interface. The inclusion of a 1.33x fractional charge pump
mode increases 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 2.5 V to 5.5 V.
The EN/SET logic input functions as a chip enable and a “1−wire”
addressable interface for control and current setting of all LEDs. Three
groups of two LEDs can be configured with independent LED currents
between 0.25 mA and 32 mA.
The device is available in a tiny 16−lead TQFN 3 mm x 3 mm
package with a max height of 0.8 mm.

Pin Function
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 2.5 V to 5.5 V. Whenever the input supply falls
below the under−voltage threshold (2 V) all the LED
channels will be automatically disabled and the device
register are reset to default values.
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.
LEDxx provide the internal regulated current for each of the
LED cathodes. These pins enter high−impedance zero
current state whenever the device is placed in shutdown
mode.
EN/SET is the enable and one wire addressable control logic
input for all LED channels. Guaranteed levels of logic high
and logic low are set at 1.3 V and 0.4 V respectively. When
EN/SET is initially taken high, the device becomes enabled
and all LED currents remain at 0 mA. To place the device
into zero current mode, the EN/SET pin must be held low for
more than 1.5 ms.
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.
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.

Basic Operation
At power−up, the CAT3636 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 (after a fixed delay
time of about 400 ms). In 1.33x mode, the output voltage is
approximately equal to 1.33 times the input supply voltage
(less any internal voltage losses).
device will automatically switch to the 1.5x boost mode
(after a fixed delay time of about 400 ms). In 1.5x mode, the
output is approximately equal to 1.5 times the input supply
voltage (less any internal voltage losses).
If the input voltage fails more or is still insufficient to
drive the LEDs, it will automatically switch again into 2x
mode where the output is approximately equal to 2 times the
input supply voltage (less any internal voltage losses).
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
If the input voltage is insufficient again or falls to a level
where the regulated currents cannot be maintained, the

Data in a register is reset once it is selected by the address
pointer. If a register is selected but no data is programmed,
then the register value is reset back to its initial default value
with all data bits to 0.
Once the final rising edge of the data pulses is
programmed, the user must wait 1.5 ms before
programming another address. If programming fails or is
The current in each of the six LED channels is
programmed through the 1−wire EN/SET digital control
input. By pulsing this signal according to a specific protocol,
a set of internal registers can be addressed and written into
allowing to configure each bank of LEDs with the desired
current. There are six registers: the first five are 4 bits long
and the sixth is 1 bit long. The registers are programmed by
first selecting the register address and then programming
data into that register.
An internal counter records the number of falling edges to
identify the address and data. The address is serially
programmed adhering to low and high duration time delays.
One down pulse corresponds to register 1 being selected.
Two down pulses correspond to register 2 being selected and
so on up to register 6. T and T must be within 200 ns to

Upon power−up, the device automatically starts looking
for an address. The device requires a minimum 10 ms delay
(T
) to ensure the initialization of the internal logic at

power−up. After this time delay, the device registers may be

Figure 21. If no falling edge is detected within 100 ms of

Once the final rising edge of the address pointer is
programmed, the user must wait 500 ms to 1000 ms before
programming the first data pulse falling edge. If the falling
edge of the data is not received within 1000 ms, the device
will revert back to waiting for an address.
To power−down the device and turn−off all current
sources, the EN/SET input should be kept low for a duration

of 1.5 ms or more. The driver typically powers−down

Register REG1 allows to set the mode and select the pairs
of LEDs to be turned on. A low LED current mode exists to
allow for very low current operation under 4 mA per
channel. If IMODE equals 1, the high current range is
selected up to 32 mA. If IMODE is set to 0, all currents are
divided by 8. Each bank of LEDs (A, B or C) can be turned
on independently by setting the respective bit ENA, ENB,
ENC to 1, as shown in Table 7. For example, to enable all 6
LEDs in low current mode, REG1 is programmed to 0111

REG6 contains the return lockout (RTLKO) bit. This
stops the charge pump returning to 1x mode. One pulse sets
it to 1. Two pulses or no pulses set RTLKO to 0. When
RTLKO is set to 1, the charge pump cannot automatically
return to 1x mode when in one of the charge pump modes.
The device can however move from 1x to 1.33x to 1.5x to
2x if the input voltage is not sufficient to drive the
programmed LED currents.
REG6 also triggers a charge pump reset as soon as it is
addressed. This forces the charge pump to start from 1x
mode and reassess the correct mode it should be in to drive
the LEDs most efficiently. If the input voltage has risen or
the device has been reprogrammed to other LED values, it
is recommended to trigger this reset allowing the charge
pump to run in the most efficient mode.

Register REG2 allows to set the same current for all 6
channels. REG3, REG4, REG5 allow to set the current
respectively in banks A, B and C. The three banks can be
programmed with independent current values.
The CAT3636 enters a “zero current” shutdown mode if
EN/SET is held low for 1.5 ms or more. All registers are
reset back to zero when the device is placed in shutdown.

Unused LED Channels
LED Selection
For applications with only four or two LEDs, unused LED
banks can be disabled via the enable register internally and
left to float.
LEDs with forward voltages (V ) ranging from 1.3 V to
5.0 V may be used with the CAT3636. Selecting LEDs with
F
lower V is recommended in order to improve the efficiency
F
For applications with 5 LEDs or less, unused LEDs can
also be disabled by connecting the LED pin directly to
VOUT, as shown on Figure 22. If LED pin voltage is within
1 V of VOUT, then the channel is switched off and a 200 mA
test current is placed in the channel to sense when the
channel moves below VOUT – 1 V.
by keeping the driver in 1x mode longer as the battery
voltage decreases.
For example, if a white LED with a V of 3.3 V is selected
F
over one with V of 3.5 V, the CAT3636 will stay in 1x mode
F
for lower supply voltage of 0.2 V. This helps improve the
efficiency and extends battery life.
External Components
The driver requires two 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.
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

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.
If an LED is disconnected, the output voltage V

automatically limits at about 5.5 V. This is to prevent the
output pin from exceeding its absolute maximum rating.
