The CAT32 is a DC/DC step up converter that delivers
a regulated output current. Operation at a constant
switching frequency of 1.2MHz allows the device to be
used with very small value external inductor and
ceramic capacitors.
The CAT32 is targeted to drive multiple white lightemitting diodes (LEDs) connected in series and
provides the necessary regulated current to control
the brightness and the color purity. An external
resistor RSET controls the output current level. LED
currents of up to 40mA can be supported over a wide
range of input supply voltages from 2V to 7V, making
the device ideal for battery-powered applications.
A high voltage output stage allows up to 4 White LEDs
to be driven in series. Series drive provides inherent
current matching.
APPLICATION
„
„
„
„
„
„
LED dimming can be done by using a DC voltage, a
logic signal, or a pulse width modulation (PWM)
signal. The shutdown input pin allows the device to be
placed in power-down mode with “near zero”
quiescent current.

Portable MP3 players
In addition to overcurrent limiting protection, the
device also includes detection circuitry to ensure
protection against open-circuit load fault conditions.

OPERATION
The CAT32 device is a high efficiency, constant
frequency, current regulating boost converter.
as possible. A low LED pin voltage ensures high
efficiency.
The device includes a switch and an internally
compensated loop for the regulation of the LED
current.
Current through the internal power switch is
continuously monitored cycle-by-cycle. If the current
limit is exceeded, the switch is immediately turned off,
protecting the device, for the remainder of the cycle.
Operation can be best understood by examining the
block diagram. The RSET pin is regulated at 100mV
and the current through the external resistor will set
the regulated current in the LEDs (from 5mA to 40mA)
with a multiplication factor of 225.
PWM dimming operation can be achieved by
switching the SHDN
¯¯¯¯¯ pin or by pulling the RSET pin
higher than 0.1V.
While maintaining LED current regulation, the CAT32
automatically adjusts the LED pin voltage to be as low

CAPACITOR SELECTION
Low ESR (equivalent series resistance) capacitors
should be used at the output to minimize the output
ripple voltage. The low ESR and small package options
available with multilayer ceramic capacitors make them
excellent choices. The X5R and X7R capacitor types
are preferred because they retain their capacitance
over wider voltage and temperature ranges than the
Y5V or Z5U types. A 1.0µF or 2.2µF output capacitor is
recommended for most applications.
Low profile ceramic capacitors with a 1mm maximum
height/thickness are available for designs height
requirements. Ceramic capacitors also make a good
choice for the input capacitor, which should be
mounted as close as possible to the CAT32. A 2.2µF
or 4.7µF input capacitor is recommended. Table 2
shows a list of several ceramic capacitor
manufacturers. Consult the manufacturers for detailed
information as new products and package options are
introduced regularly.
The voltage rating of the output capacitor C2 depends
on the number of LEDs driven in series. A 10V
ceramic capacitor is recommended when driving two
LEDs. A 16V ceramic capacitor is recommended
when driving 3 or 4 LEDs.

CAT32
DIODE SELECTION
two parallel strings of LEDs for greater light output,
resulting in 30mA to 40mA (two strings of 15mA to
20mA) flowing into the LED pin.
Schottky diodes, with their low forward voltage drop
and fast switching speed, are the ideal choice for high
efficiency applications. Table 3 shows several
different Schottky diodes that work well with the
CAT32. Make sure that the diode has a voltage rating
greater than the output voltage. The diode conducts
current only when the power switch is turned off
(typically less than one-third the time), so a 0.4A or
0.5A diode will be sufficient for most designs.
LED DIMMING WITH PWM SIGNAL
PWM brightness control provides the widest dimming
range (greater than 20:1). By turning the LEDs ON
and OFF using the control signal the LEDs operate at
either zero or full current, but their average current
changes with the PWM signal duty cycle. Typically, a
5kHz to 40kHz PWM signal is used. PWM dimming
with the CAT32 can be accomplished two different
ways.

The ¯¯¯¯¯
SHDN pin can be driven directly or a resistor
can be added to drive the RSET pin. If the ¯¯¯¯¯
SHDN
pin is used, increasing the duty cycle will increase
the LED brightness. Using this method, the LEDs
can be dimmed and turned off completely using the
same control signal. A 0% duty cycle signal will turn
off the CAT32, reducing the total quiescent current
to near zero.
LED CURRENT PROGRAMMING
The LED current is programmed with a single resistor
connected to the RSET pin The RSET pin is internally
regulated to 100mV, which sets the current flowing
out of this pin, ISET, equal to 100mV/RSET. The
CAT32 regulates the current into the LED pin, ILED, to
225 times the value of ISET. For the best accuracy, a
1% or better resistor is recommended. Table 4 shows
several typical 1% RSET values.
RPWM = RSET × (
If the RSET pin is used, increasing the duty cycle will
decrease the brightness. Using this method, the LEDs
are dimmed using RSET and turned off completely
using ¯¯¯¯¯
SHDN . If the RSET pin is used to provide PWM
dimming, the approximate value of RPWM should
be calculated (where VMAX is the “HIGH” value of the
PWM signal):

In addition to providing the widest dimming range,
PWM brightness control also ensures the “purest”
white LED color over the entire dimming range. The
true color of a white LED changes with operating
current, and is the “purest” white at a specific forward
current, usually 15mA or 20mA. If the LED current is
less than or more than this value, the emitted light
becomes more blue. Applications involving color
LCDs can find the blue tint objectionable.
When a PWM control signal is used to drive the
¯¯¯¯¯
SHDN pin of the CAT32, the LEDs are turned off and
on at the PWM frequency. The current through them
alternates between full current and zero current, so
the average current changes with duty cycle. This
ensures that when the LEDs are on, they can be
driven at the appropriate current to give the purest
white light. LED brightness varies linearly with the
PWM duty cycle.
For other LED current values, use the following
equation to choose RSET.
R SET = 255 ×

LED DIMMING WITH A LOGIC SIGNAL
PCB Layout Guidelines
For applications that need to adjust the LED
brightness in discrete steps, a logic signal can be
used. RMIN sets the minimum LED current value
(when the NMOS is OFF):
The CAT32 is a high-frequency switching regulator
and therefore proper PCB board layout and
component placement can minimize noise and
radiation and increase efficiency. To maximize
efficiency, the CAT32 design has fast switch rise and
fall times. To prevent radiation and high frequency
resonance problems minimize the length and area of
all traces connected to the SW pin and use a ground
plane under the switching regulator.
RMIN = 255 ×
0.1V
ILED(MIN)
RINCR determines how much LED current increases
when the external NMOS switch is turned ON.
RINCR = 255 ×
The switch, schottky output diode and output
capacitor signal path should be kept as short as
possible. The ground connection for the RSET resistor
should be tied directly to the GND pin and not be
shared with other components.
