CAT37
CMOS White LED Driver
Boost Converter
Description
The CAT37 is a DC/DC step up converter that delivers a regulated
output current. Operation at a constant switching frequency of
1.2 MHz allows the device to be used with very small value external
inductor and ceramic capacitors.
The CAT37 is targeted to drive multiple white light ? emitting diodes
(LEDs) connected in series and provides the necessary regulated current
to control the brightness and the color purity. An external resistor R1
controls the output current level. LED currents of up to 40 mA can be
supported over a wide range of input supply voltages from 2.5 V to 7 V,
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.
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”
