Dad has l’IS31LT3117, a driver with four linear channels for high brightness LEDs. With a range of operating voltages between 6The e 53V, the product is able to absorb up to 350mA per channel. Should such an increased current, the four outputs can be connected in parallel for 1,4amps (4 x 350mA).
The LED driver also addresses the challenges of thermal management thanks to 16pin TSSOP the, for optimal heat dissipation, and further including support thermal characteristics of transistors external to disperse any excessive heat. The junction temperature of the driver is constantly maintained below 160 ° C; avoid shutdown, la corrente in uscita viene comunque ridotta del 2.22%/°C quando la temperatura supera i 130°C. If grades were to continue to rise, going over 160 ° C, the device will automatically turn off, interrupting the supply of current to the LEDs.
Il nuovo IS31LT3117 consente inoltre significativi risparmi in termini di costi, operand for example in 48VDC. Compared with a single-channel driver 24V, the account of the components can be reduced from 25 pieces in a handful of components.
