DC1160A: 330mA @ 40V Max, 3 ~ 40V in
The LT3518 has a 45V switch with 2.3A peak switch current limit rating. DC1160 has overvoltage protection at 40V if the LEDs are open or not properly attached to the terminals on the PCB. The shutdown function is activated by pulling the shutdown terminal to ground.
The high side PMOS PWM dimming MOSFET can be used to achieve 3000:1 PWM dimming ratio. The board is programmed for 1MHz oscillator frequency, but can be adjusted by changing R14. Higher frequency results in higher PWM dimming ratio.
A few simple modifications can be made to DC1160 in order to convert the board from a boost LED driver to a buck mode or buck-boost mode LED driver. Please consult the data sheet for schematic details and the factory for customization details.
