Triple Output LED Driver Drives Up to 24 x 500mA LEDs & Offers 3,000:1 True Color PWM Dimming
The LT3496 senses output current at the high side of the LED, enabling buck, buck-boost or boost configurations. With an external sense resistor, the user programs the output current range of each channel. Each of the three independent driver channels utilizes an internal 750mA, 45V NPN switch and has a built in gate driver for PMOS disconnect. Other features include open LED protection and thermal limiting.
The LT3496EUFD is available from stock in a thermally enhanced 28-lead 5mm x 7mm DFN package. 1,000-piece pricing starts at $3.50 each and it is available from stock.
The LT3496IUFD is tested and guaranteed to operate from a -40°C to 125°C operating junction temperature and is available from stock.
