CAT4134  
500mA Dual Channel Movie/Flash LED  
Driver  
FEATURES  
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 3V is  
supported, making the device ideal for Li-Ion battery  
applications.  
„ Dual Mode (Movie or Flash) operation  
„ Independent Movie/Flash LED current control  
„ Can drive 2, 3, 4 or 6 LEDs  
„ High LED Current (250mA max per channel)  
„ Power efficiency up to 85%  
„ Dual frequency mode 1.2MHz and 900kHz  
„ Soft-start inrush current  
„ Adjustable overvoltage protection  
„ Thermal shutdown protection  
„ Operating temperature range -40ºC to +85ºC  
„ 12-pad TDFN 3mm x 3mm package  
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.  
APPLICATIONS  
„ Camera flash  
„ Flash light  
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 3mm x 3mm.  
„ High-power white LEDs  
„ Digital still cameras  
„ Color LCD backlighting
