description

LT®The 3475/LT3475-1 is a dual buck-type DC/DC Light. High-side current sensing allows the operation of the LED at the load ground electrode. High; Output current accuracy is maintained over a wide current range (from 50 mA to 1.5A), providing a wide optical range. The unique PWM circuit achieves a 3000:1 modulated light range, thus avoiding the color drift common in LED current-modulated light operation.

The high switching frequency provides many advantages, allowing the use of small inductors and ceramic capacitors, small inductors and 20-pin TSSOP packages

With its wide input from 4V to 36V; range, the LT3475/LT3475-1 can regulate a variety of supplies. Current mode PWM
