Lighting > LED Drivers - DC In DC994A: 350mA x 3 Ch, 3 ~ 40V in Manufacturer: Analog Devices Inc.

Demonstration circuit 994 features the LT3003 three channel LED ballaster with PWM in a 10-lead MSOP thermally enhanced MSE package. The demonstration circuit is designed to ballast three channels of LED current from 100mA to 350mA per channel. The PWM dimming function of the LT3003 eliminates the need for discrete MOSFETs. The LT3003 internally performs the level-shift required for non-ground re…
