CAT4134 - 500mA 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.

Features

  • 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.
