LT3796/LT3796-1  
100V Constant-Current and  
Constant-Voltage Controller  
with Dual Current Sense  
DescripTion  
The LT®3796/LT3796-1 are DC/DC controllers designed to  
regulate a constant-current or constant-voltage and are  
ideal for driving LEDs. The fixed frequency and current  
mode architecture result in stable operation over a wide  
range of supply and output voltages. Two ground referred  
voltage FB pins serve as the input for several LED protec-  
tion features, and also allow the converter to operate as a  
constant-voltage source. The LT3796/LT3796-1 feature a  
programmable threshold output current sense amplifier  
with rail-to-rail common mode range. A separate high  
side amplifier is gain configurable with two resistors and  
can be used to regulate a second current or a voltage  
in combination with one of the FB pins. The PWM input  
provides LED dimming ratios of up to 3000:1.

switch, either to drive a second LED string or to extend  
analog dimming range.
