CAT4134 Datasheet (On Semiconductor) - Dual Channel LED Driver

CAT4134, Dual Channel LED Driver

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 se
