CAT4134
500 mA Dual Channel
Movie/Flash LED Driver
Description
The CAT4134 is a high power, dual channel boost converter which
provides two matched LED currents. Output current levels are
controlled by one of two resistors RSET or RFLASH. When the
FLASH input pin is low (movie mode), RSET sets the current. When
FLASH is high (flash mode), the resistor RFLASH sets the LED
current. Each channel drives two or three white LEDs in series and
provides a regulated current to control their brightness. Input supply
down to 3 V is supported, making the device ideal for Li ? Ion battery
applications.
High frequency low noise operation allows the device to be used
with small external inductors and ceramic capacitors while still
maintaining excellent efficiency. When not in use the device can be

placed into a “zero” quiescent mode via the shutdown pin.
In addition to soft-start control and current limiting, the CAT4134
include thermal shutdown protection. A dedicated overvoltage pin
(OVP) allows the user to limit the maximum LED supply voltage. The
device is packaged in the 12 ? pad TDFN 3 mm x 3 mm.
