Overview
CAT4134
LED Driver, Dual Channel Movie/Flash, 500 mA
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 cera...
